> On the internet there are calls to violence in any political group, even vegans and cat lovers. We ignore that because they aren't relevant. But if you seriously crack down on cat lovers, you might need to expect real violence.
And vegans and cat lowers do seriously take them down in their forums when those cross the line. And when they discuss cats and food on reddit and reddit deletes accounts of those who threaten violence, the vegans and cat lowers are happily continue to discuss cats and food.
This is bad analogy.
