Oh yeah, but honestly if we can just keep the big troublemakers out and set a line in the sand we can put up with the fuzzy edge cases. It would also be necessary to consider tolerance a concept that goes beyond interpersonal interaction. Like, okay, this guy is civil but what he's saying is that genocide is okay. Or, okay, this guy is rubbing me the wrong way but at its core "Archer is a better Captain than Sisko"* is not fundamentally about race, it could honestly be he just prefers Archer.
*Sisko is a better Captain than Archer, this is fact. But sometimes people are just wrong and that's okay.
