Erm, no. That can't be right, because then you can simply say that literally anything is an X-religion practice simply because some self-described adherent somewhere claims that it is. That leaves no way to differentiate between acts that are actual tenets of a particular religion, and acts which are cultural or personal, or which are the result of mental illness.
You
can simply say that
literally anything is an X-religion practice because an adherent claims that it is. No, you
can't differentiate between acts that are actual religious tenets and those that are cultural, personal, or the result of mental illness. Consider that the vast majority of religious belief centers around invisible beings who watch your every move and who will punish you if you don't do what they want. Sometimes they even talk to you, make you hallucinate, or burn your bosom.
That's mentally freakin' ill.
Murdering abortion doctors is not a Christian act, because it directly violates the tenets of Christianity as laid out in the accepted body of scripture, taken in context. It's no different from someone claiming to be a doctor, regardless of medical training or lack thereof, and going around cutting bits off of people to save them from cancer.
Doctors have the AMA, and the government pointing to it saying "if these guys say you aren't a doctor, you aren't a doctor." Personally, in the case of chiropractors, faith healers and other such "I'm not saying I'm a doctor, but I'm a doctor" woo, I wish the gov't would point a good deal harder than it currently does.
Religion has quite a lot of different groups who would love to put themselves forward as the AMA, but without any god at all to point to them and say "this is the one. These guys, they're my bros," every opinion is
exactly as valid as every other. There is no accepted body. There are no tenets. Religion does not run on
consensus.
To claim it's a Christian act requires a tortured attempt at justification enabled by cherry-picking pieces out of context, redefining them to fit said justification. And often the proponents of such murder do not have even that, only bald assertions, or "personal revelation", without any real attempt at scriptural justification. Just as claiming FGM is an Islamic act requires similar cherry-picking and unsupported assertions. There are certainly many different "flavours" of Christianity, Islam, Buddhism, etc. depending on which aspects or interpretations of scripture are most emphasized; but there are always core tenets that unite all the disparate groups. Violation of those tenets must necessarily mean that the violator is outside that group, and not a true member of said group. (Remember, No True Scotsman is only a fallacy if the basis for judgement is not a defining criteria of belonging to the group.)
Being
Christian requires a tortured act of justification. It doesn't matter how convoluted a person's beliefs have gotten to get them where they are, they're still their beliefs. That person has a right to them and neither your nor I can order them otherwise, and versa vice. Remember, Argumentum Ad Populum is still a fallacy even if you and everyone else wants it not to apply.
That is exactly the conflation that the APlussers are guilty of, conflating both positive or negative acts of individuals with the tenets or characteristic of a larger group and claiming that group is inherently good or bad because X. That there is an "X culture" that all right-minded people should be vehemently opposing, despite the complete lack of any evidence of a prevailing culture.
It's important when making any associations to differentiate between variations based on interpretation, and direct violation of criteria defining the group. Claiming a "rape culture" because some individuals of said culture commit rape is a fallacy, as there is no indication that the inherent characteristics of the group, in this case mainstream Anglo-American culture, condone rape, let alone create a "culture" of rape, and quite a bit of evidence to the contrary. But if you cherry pick comments and actions of a few aberrant individuals, and take the vagaries of difficult rape cases out of context, you can build a specious justification for claiming that such a rape culture exists despite an overwhelming cultural antipathy towards rape and rapists.
Why do you keep accusing me of this? Didn't I just get through saying I'm not intending for this to be a vector by which others of the same faith could be impugned?
Would it help if I pointed out the opposite was also true: that if someone says something is
not an element of their faith, it isn't, even if other adherents disagree?
To give an example, an American Muslim can say that suicide attacks are not an Islamic practice, and be perfectly correct. Meanwhile, an Iranian Muslim can say that suicide attacks
are an Islamic practice, and
also be correct. What
isn't correct is to say that the Iranian Muslim's suicide attack isn't an Islamic practice because the American Muslim said so.
