> Whynot use the correct word for it, which is prejudice?

Again you seem more concerned with grammar than, y'know, condemning racism, prejudice, or bigotry. They're all equally bad and closely related concepts. "A rose by another name" and so on.

Your own comment has 3 typos and several grammatical errors ("prejudiced to" is wrong, for example). Irony.

Finally, modern usages of "racism" encapsulate all of these meanings. Languages change over time.

> You can be prejudiced to any group of people, doesnt mean that you are biggoted

Yes, that's literally what it means.
