The internet has a big "dogs barking at each other through the closed gate" dynamic. People are much more rude and aggressive to each other from a safe distance.

The safe distance is anonymity. A few of the bold ones that are all in on the grift or just genuine assholes will own their opinions and behaviour.

All the little followers have a different tune when confronted with a real social situation, at least one that isn't a mob providing safety in numbers.

It's similar to the bully dynamics at school. Get one of the hangers-on by themselves and they are civil with you. When they are with the bully peer-pressure stops them from thinking for themselves.
