What bollocks, most "ideas" people are trying to surpress like white nationalism and sexism aren't being surpress because people are secretly scared that whites are the master race or women are inferior, they're being surpress because they're objectively harmful ideas that have caused enormous suffering throughout human history.
The idea that people are trying to stop the spread of these ideologies because they're "secretly scared they're correct" is nothing but a way for people who hold these harmful views to justify having them through defending some self delusional "truth" they've substantiated purely through nonsense.
