It's a thing now banded about like confetti we all have our own ideas what it means. The British law is clear racisim is anything perceived to be racism by the victim or I think also by a third party. Which is pretty open ended you think it is and it is.
So I would like to hear what other posters believe racism is.
My own opinion is where you overtly discriminate because of the colour of their skin (any skin) for white people can be victims of racism and in today's world very often are. It also needs to be identifiable otherwise surpious claims can be made and the law is weak. Which I think it is and in today's world needs to be amended
However that is just my opinion how do you see it ?
Racism for me is when a person of a certain race/religion/citizenship/caste considers people of a different race/religion/citizenship/caste inferior, only because of their differences. Black slavery by white people was racism because white people considered themselves superior to the black. There are people who were enslaved after being made prisoners of war for example, this was not racist if them being made slaves didn't have anything to do with the person's race.
I would add, racism is not only about colour of skin, for example, if a UK citizen thinks he is superior to a polish, despite both being white, is racism to me. The Nazis considered themselves superior to the East Europeans and Jews, even white, this was racism.
The British Empire was based in racism as it considered all the natives of its colonies inferior.
