Foxx sounds like a self indulgent jerk.'I come into this place to do a photo shoot and they got Ritz crackers and cheese.
'I'll be like, ain't this a b***h. Y'all didn't know black people was coming.'
Often, when someone treats a Black person wrongly, in their eyes anyway, it's 'racism'. To a woman it's sexism, to a Muslim it's Islamophobia, to a Gay it's homophobia.
The fact is that people behave badly regularly, often without meaning to, or no harm was meant.
I'm a White guy and none of the above so when someone is rude to me I accept that the person is being rude to me. I have no fallback position that this person is being racist, sexist, or homophobic, it's just a rude person. That's life and we have to learn to deal with it, and not fall back on the cheapest possible ( and whiniest) explanations.
