I'm pretty conflicted on this issue overall, but I don't think it's entirely nuts to hold the President of the US to a higher standard than many other accounts.

Be completely honest to a stranger:

When you see content like you are talking about, do you report it using the websites’ tools? Please be honest.

I know what you mean, but that's an insult to actual liberals. You're referring to leftists. They hijacked "liberal" some time ago.

When someone is high profile they will be treated differently. That's just the nature of being high profile. Trump has said a lot of things that would have gotten you or I banned if Twitter noticed. Twitter let Trump slide for a long time, and is finally moderating some of the most egregious examples.

And to be clear, anyone calling for violence should also have similar actions taken against them. But, me shouting get out the guillotine to my 10 followers is different than POTUS saying the same thing.
