A very short-sighted point of view. What happens of down the road someone decides what you think, believe, or say, is wrong?
I'd quote Niemöller but I fear it would fall on deaf ears, (or blind eyes, I guess).
I'll start worrying someone will stop protecting my right to speech when I call for the deaths of all people fitting some category.
It's that simple.
ie- This isn't about their beliefs, it's about the right to free speech. If no one stands up now, who will be left to stand for you when your time comes.
edit- I once had to take a friend of mine to her abortion appointment. The vitriol screamed at us both (they assumed incorrectly I was the father), was mind-blowing. They brought her to tears, were screaming in her face. It got ugly until I screamed right back. The fury I felt that day was incomprehensible to most people. Literally saw red. Had to comfort my friend afterwards. To me it was evil, spiteful, hateful shit to spew at someone at their lowest and most vulnerable.
They still had the right to spew that garbage.
The times it's hard to swallow can sometimes be the most important.
