I think human's innate biological need to be dominant (in the past that's who survived and was successful at spreading their bloodline.) It happened with racism, it happens in religion (and how they treat both LGBT and atheism ) led us to this weird point where we feel the need to always feel as if we have the "higher ground" as in many just always want to feel "superior no matter the cost (see poor people voting against their own interests, or even immigrants siding with closing borders) It's crazy how many people will simply allow themselves and people like them to be absolutely torn apart, simply to make sure others don't have things. It's almost as incredible as to how many just want to cover their eyes and ears when "systematic racism" gets brought up to anyone that's straight/white and male.

Hell If I never would of went to college for psychology and psychological science and not had to take a bunch of filler courses I never would have understood as to just how deeply ingrained our own biases are. People also probably only hold their tongue nowadays because this volatile political climate we're currently in and not many want the label of "beta cuck SJW" placed over their heads.

It sucks cause we've been trained since birth that we don't want to end up as *insert lowly food worker/homeless person/ low income dweller here* and when we spend quality time with people that have remotely different lifestyles than us, these biases tend to dissipate.
