Well of course they do. The whole point of the argument is that LFJ is so hellbent on trying to take Josh's site down in any and all ways possible, every single day, continually for years, and people are letting them get away with it. They both have axes to grind with each other.
If you had swarms of people that wished you dead and did everything they could to mess with you for years and years, you'd get angry at people too. You may not agree with his conduct but I think he is still fighting a good fight nonetheless. It's not like he has fled the country for no good reason.
If he just wanted kiwifarms to be a gossip forum he could have banned doxxing.
He doesn't allow doxxing out of a commitment to free speech. The forum doesn't actually have that much free speech. If you criticize him you will get banned pretty fast.
There isn't much transparency either. Banned users aren't marked as being banned. And bans are often done without public notification. So unlike most forums, you can't tell if someone has been banned.
If you fix that, then people might take it more seriously. At the moment it looks more like you have an axe to grind.
