If your biggest problem is that you object to using "people of colour" rather than "coloured people", I envy you.
no, I object to people getting called out on it and made to look bad over something that shouldn't matter.
It's making enemies out of potential allies. Who cares if I use the word "colored people" if I'm reducing the headcount of KKK members on a nightly basis*?
It's not the change of words. It's the insistence of offense where none is intended for the goal to further a cause.
Ultimately, all I've learned from this thread is that it is downright dangerous to talk about race. Ever. Good luck fixing a problem when people are afraid to talk about it.
