could someone explain this? https://i.imgur.com/1tS201x.jpg

As someone who has no interest in politics, I have maybe begun to realize the need for it in today's political climate. I have always found it useless to discuss politics among my peers. Literally all of them utilize emotion at such a degree it is impossible to have a conversation as a devil's advocate without being seen as some fucking crazy person. (at a liberal ivy league college). While I have found the reading list on this site to learn more about politics, I just am wondering what is the "white western civilization" and why is it natural for one to turn more conservative after educating themselves?

Thank you
