why are people racist?Watch
I think it’s all down to ones own feeling of inferiority
For example, the shocking, (mostly) Pakistani grooming gang scandal. This had Pakistanis, Indians and Bengalis involved who are all of brown skin.And a few close minded people then begin to think that every brown person is like that. (Theres over 5 million South Asians in the UK, I don't think were all groomers).
Then you can take the stereotype of Black people being thieves and robbers, people of all race/religion are thieves, however society (Mostly Media) has painted a picture into our minds to assume things.
Honestly the only way to beat having a racist mentality is going out and making friends with people from all walks of life, if you ever go to a racist person they have probably never even had a real conversation with the minority they hate, or may have had a bad experience with one and then put every other person who happens to be white/black/brown in the same bag (Yes white people can also be discriminated against, despite what some people on here think)
Personally, being a brown guy myself i've never been the subject of racial abuse, apart from when you go to posh areas and you get a few people staring at you, thats it.
It’s the same reason why a group of football hooligans wearing blue shirts may express animosity towards another group wearing red shirts, even though none of them actually know each other.
