why do people hate the word n e g r o how is that a racist word?

It used to be a normal acceptable word until some black American leaders in the United States during the civil rights movements era in the 50s and 60s "objected to the word because they associated it with the long history of slavery, segregation, and discrimination that treated African Americans as second class citizens, or worse" and decided the words "black" or "African-American" were more acceptable.

it all depends on how you use it

I'm old enough to remember when n e g r o (which of course is Spanish for "black") and "colored people" (as in the NAACP - National Association for the Advancement of Colored People) were standard, and calling a colored person "black" was considered insulting. Why the change? Something to complain about IMO, like changing Bombay to Mumbai for no reason, or complaining that centuries-old standard terms like Eskimo and Gypsy are racist, because that's not what they call themselves. Somehow the Deutsch don't seem to mind being called Germans.

There is a long history of it being used as a pejorative.
