If I called you an "ugly Jew" it would be an insult. You might be ugly and you might be Jewish. However it's an insult regardless of it's factual accuracy. Get it?
This is more sarcasm. You chastise me for being "loud and aggressive"(though I don't see how I can even be loud in an internet forum) yet you continue to insult me? Do you think you'll get your point across insulting people?
What if I found other people who were ugly and posted pictures of them claiming that because they were ugly it was not an insult to you because you were not the only ugly person? Don't answer that.
I find that getting aggressive and loud with people tells them that you're serious and makes them take you seriously.
Being aggressive in your arguement can also have the complete opposite affect and turn people off to what you are saying.
