You say “we all know what they mean” but it really isn’t clear. I’ve met people saying “racist” just refers to all white people. I’ve seen “intolerence” refer to transsexuals merely saying we exist, while hating on transsexuals is “tolerance”.

Perhaps I’ve been in political discussions too long. The words on the surface are obvious. Be chill, don’t attack people for the way they were born, etc. but people who strongly vocally oppose “intolerance and racism” often don’t mean that. they take “racist” to mean “simply commenting on race in a way they disagree with” and “intolerance” to mean “disagree with them”.

I’m always wary of when people are crying to censor someone, because historically those doing the censoring have not used their power fairly.
