People tend to be insecure and greedy. They are afraid they will lose something if they try to equalize opportunities, status, and access to wealth.
Cuz humans are judgmental pieces of crap who only care about themselves and what's considered the social norm of the time and such. No one cares to see others for who they really are. Makes me sad.
Thank you, just being honest. :)
