I grew up in a very religious, rural part of the country (US) and in a time when sexism and racism were the norm. I’m now an atheist and now recognize how damaging all of that is to the individuals it harms and to society as a whole.
Lots of people who are atheistic and urban are just as sexist and racist. They just don’t talk about it quite the same way.
I live in the northeastn. Racism here isn’t slurs or loud talking about how bad people are. Racism here is calling the cops because there is a single black guy minding his business smoking in the park and it makes you scared.
