WHY IS IT OKAY TO CALL ROMANIAN'S GYPSY?

OK I SEEN PEOPLE REFERRING  TO ROMANIAN'S AS 'GYPSY'
AND GYPSYS DONT LIKE THAT.

SO IS IT NOT! OKAY TO CALL A BLACK MAN A 'NIGGER.

OR A WHITE MAN A 'TRAILOR PARK TRASH?
 
OR AN ITALIAN A 'GUIDO

OR A MEXICAN A 'SPICK?

JUST TO NAME A FEW, TO SET AN EXSAMPLE..
AND PLASE DO TAKE THIS OFFENSIVE
I AM ONLY ASKING

I can call whomever I want whatever the fuck I want. It's called freedom of speech, pinko.
