Those who married within your caste..

Why would it be rude to question something I believe is inherently wrong just because it doesn’t affect me? Does that mean white ppl should have kept their mouths shut about apartheid as well.. If I think people are being prejudiced of course I’ve got the right to say something.. The sooner this system dies out the better imo. I can sort of understand that some ppl feel they can’t upset their parents even tho I don’t agree with it myself, but when girls and guys in this generation say they want to uphold this rubbish because** they themselves believe in it** I think that’s really messed up..
