Dude, he's mocking you all and you don't even get it. The more you scream the more attention you're bringning to his magazine.
Other people are not as stupid as you think. But the question between not giving it attention to challenge it and possibly giving it food to fester or not giving it attention and also not challenging it is not easily answered. Looking at the repulsive backlash, drawing attention to it was the right choice. Sure, some more people might flock there, but the vast majority strongly disapproves and now knows that kbin.social (unsurprisingly) has awful people on it as well.
How is one guy saying (to extremely paraphrase) "some people have used the label of freedom to exploit vulnerable people" relevant to this? Like, thats a given, that some people will use this as a guise. Now, is there a systematic problem of leftists arguing for the freedom to assault children? No, only in the imagination of projecting right-libertarians.
