The term wop came about when Italians started migrating in droves to America in the early 1900's - it means without passport. Basically the equivalent of calling someone an illegal immigrant. But the intent is to be fowl and cause mental anguish.

Guinea is basically like calling a mixed baby an Oreo.

... It's meant to be racist, and I grew up in it...

Some people care, some don't.

When people bash on Italians I just assume it's because they can't cook, or conduct business, have bad taste and have small dicks.
