I don't like racism but, I do believe privately owned businesses have a right to let in who they want and don't want. I see it all the time, actually. I remember my friends always saying how he'd get in clubs because he had a bunch of hot females with him, while other guys were left outside because of the way they dress or didn't have hot females with them. So there is discrimination based upon gender and clothing / outward appearance already happening.
Of course, I think it's not moral to judge someone solely by the look of their face or color of skin alone but, if that business has had a history of people that share very similar thug-ghetto culture, I cannot entirely blame them for not wanting them there, if the business didn't want to risk something bad happening to begin with.
And I'd say the same thing if a 'black' owned business today didn't let a group of 'white' goth or heavy metal kids in based upon history (let's imagine, for argument sake) of their thug-like cultural behavior.
If you have a private business, you've every right to pick and choose who you do transactions with and, of course, most of you know that you'd likely discriminate based upon stereotypical history, how the group is dressed, how they look in general, etc.
Let's not be hypocrites here.
If they don't like it, maybe they should not adopt a thug ghetto-like culture to begin with. That's what should be spoken about here.
I'd sympathize more if it was *solely* based upon genetic difference alone, yet no difference in culture, the way they act, etc. Then it'd be a totally different story to me.
Maybe this business had problems with the group before? No one really knows.
