The act of preventing white people from entering a place based on the color of their skin is the same thing the black's fought to get rid of. Turning around and doing the same things (like your "White people harassed blacks, so...it's not bad when black folks do it to whites" suggestion above) helps absolutely no one.
That's kind of relative though. To give you a counter-example I took exception a few years ago when I was told I wouldn't necessarily be welcome at a lesbian joint, as I couldn't understand why. I'm not homophobic, I have no issues with gay rights and it's not like I'd go in and stare at people or act weird, so how come?
But there are places people go to feel comfortable. It's not about me, it's about them.
There is still a line to be drawn somewhere but it's not probably prudent to draw it in favor of the more privileged groups in existence. It's what it is.
