The only sane response to this crap is silence. Stop legitimizing it by acknowledging its existence.
Shit exists, insanity exits, people can and will say what they want - doesn't mean every thing that's said needs to be addressed without regard to anything else.
You seem strongly convinced that there is nothing more to be said beyond your own apparently firmly held view on this subject, and I respect that. However, it appears this view is far from ubiquitous. Does misrepresenting and insulting those who do not share it seem more likely to convince them than ignoring them does?
So for you, validity of views has corelation with how many people hold it? I guess we can call that absurdity and stop?
Let's be adults and have a conversation.
