Trump wasn't banned for being a crook but for inciting violence and repeatedly breaking the terms of service. He got away with far more instances of breaking the ToS than any normal person would.

I know there is a fine line between things like Freedom Fighters/Extremists/Terrorists depending on how it's viewed and who is viewing it. Similarly inciting violence could be muddled away with enough rhetoric or only selectively enforce, as governments often do.

Likely the best solution is to update the laws around social media use or extend the previous laws to include those instances and then apply it equally to all.

All of that said though, Trump very much repeatedly broke the ToS and rightfully deserved to banned before he became president.
