Its a general observation. There are levels of bigotry and racism;
The "hard racist/bigot". They are the haters, they aggressively support white supremacists and say that people who support the victims or who would allow brown people to live and work in the country are race traitors. They blame immigrants for their own victimization, and are the most likely to become terrorists.
The "open racist/bigot". They don't like "others" (defined as anyone who is "other" w.r.t. themselves). When when asked they will say so. They think there nothing wrong with racist and religious jokes and memes. "....the Jews will not replace us"
The "soft racist/bigot". These are the "fine people on both sides" lot. Intellectual cowards who will never come out and say exactly what they think, because they don't want to actually be pegged as racists even if that is what they, and everyone else knows, they are.
The "covert racist/bigot". These are the dog-whistlers. They try to pretend they are not racists or bigots, and will do and say things that you cannot quite pin down as racism or bigotry, such as being critical of the way one group acts in support of another, victimised group. These are by far the most prevalent ones. Most of them don't even realise that what they are doing is racist or bigoted. I've even caught myself saying things that would put me in this group, particularly when I get into a discussion about the existence gods and deities.
Satisfied?
I for one am not satisfied. Where in this list of descriptions is there a place for people who are actually not bigots or racists? Accepting your category of "covert racist/bigot" your categories apply to everyone and so become meaningless.
Not to you specifically smartcookie, but to everyone here making insinuations of racism:
I have worked hard over my many years of adult life to overcome my own bigotry. When I was growing up during the 60's in a predominantly white society bigotry was common and encountered every day without giving it any thought. Words such as nig-nog, golliwog, and raghead were applied to ethnics. Homo and faggot were applied to gay men. Retard and similar were used for mentally challenged. All these people were viewed as being somehow on the fringes of society
With this ingrained into a person early in life it takes a significant effort to become aware of how those are affected by the words and the attitudes and to change ones own views for the better. I think I have made significant progress in overcoming the bigoted views of my early life. I will, like others, slip up occasionally but then I will strive to correct myself.
Because of this I am rightly offended when anyone, such as a couple of posters here, insinuates that I am consciously racist. Perhaps a little background will help those accusers realize why they are wrong.
The city where I have lived for almost 30 years has a minority "white" or as they classify it "caucasian" population according to the 2016 census. 33% of our population is of South Asian heritage and the balance are largely Chinese an Filipino. Surrey is proud to boast the largest Sikh population of any city outside India.
In the course of just going about my regular business in Surrey I am just as likely to be conversing with persons who have darker skin than myself. This is so common that a person's ethnicity mostly just becomes insignificant background info.
I love living in Surrey and take pleasure in the fact that people of different origins can live together so well. Of course racism is not unheard of, but it is uncommon enough that it will always make the local news and papers. Community groups will instantly raise the issue to further public awareness in order to do what they can to decrease future racism.
I suspect that if I was actually racist the large number of non-"white" residents here would have years ago sent me running to a whiter community.
Similarly, with LGBTQ people. I had very little knowing interaction with the community as a young man. Then I met my future wife. She had several close friends in the community and I quickly learned that my attitude needed to change. These days it is not uncommon to be at a party where my wife, myself and the children of a couple of our friends are the only "straight" people present. And that situation is just fine.
With persons with mental and physical handicaps I had my eyes opened about 25 years ago when my wife and I became foster parents. Many children in the foster care system present challenges that are just not encountered elsewhere. As part of that learning process a lot of the behaviors encountered in those challenging children made more sense and the methods used to teach them produced some remarkable results. Encountering a mentally challenged adult or child in public is not the intimidating situation I once thought.
I am not posting this to show how wonderful, or politically correct, or tolerant I am. I am really just this dude who is trying to understand the world a bit better and maybe make it a bit more pleasant. I still have a ways to go and will likely occasionally do some things that I will not be proud of till the day I die (which is really not that far away).
So enough with the implied bigotry. If I say something that may not be worded in the best way possible tell me and I may try to correct it. Otherwise, address my points and not my perceived personality.
Now, FWIW I do not have the same tolerance toward religion. I will treat all religions with similar distain. In the case of the NZ mosque shootings I am fully supportive of the individuals who have lost loved ones, and those still fighting in the hospital. This is because they are people who did not deserve this, The fact that they are muslims adds nothing.
