Why do my nonwhite neighbors get mad at me for playing my music as loud as they play theirs?

I finally got tired of being nice so this weekend I got a real rock concert loud system at the house. When ever I hear those annoying rap or Mexican songs I play Dixie and a bunch of other Johnny Rebel stuff so loud they cannot hear their junk. Just to really piss them off, I bought a 20x30 foot confederate flag to fly when I do it. When they complained I told em, I stop when you stop.
