Even people with obnoxious views (sexist, racist) aren't terrible; sexism and racism are usually a result of history and social norms not personal choice. Gently planting anti-sexist ideas in a non-confrontational way allows you to have a positive relationship with such a person without ignoring the negative aspects. The platform matters as well. Facebook is designed in such a way that self-promoters and low-brow content fill the news feed.
Yeah, I guess my point is that the norms are terrible. That we, as a people, should be better communally than we are. Like, why is there still so much intolerance when we know better? It makes us look stupid. Our portion of history will be when technology developed the fastest and people stagnated, and none of out technology will be around to be in museums because we are a culture that's very much into planned obsolescence, and everything falls apart in 5 years.
