Guess what, dude... I'm white, and I've experienced 'racism' in exactly the same manner as you... indirectly. But, it's there.
'Whoa, wait a minute'... you say! 'You're white! How did you experience 'racism'?'
i went to a JC for my first couple of years of school. The track and field team that I was a member of, was LARGELY black. I mean, to the tune of, I was the ONLY white athlete on the bus, and the other white folks were the HC, the asst. coach, trainer, and bus driver. That means that most often, the back 2/3's of the bus, was 20-30 young black athletes, and myself. Countless times, I heard conversation about "this fu-king white motherfu-ker", "that cracker", etc etc. And countless times they would catch themselves and say something like "not you, man... you're cool" Blah blah blah...
The point being... you can sit here and tell us that you've been there, you've seen it, and whatever. But, I'm here to tell you, I know for a fact that it exists 'on the other side'. And you cannot tell me that it doesn't. Oh, and also, I'm from the southwest... if you want to get into the things I heard from Mexicans about whites, let's get it.
The fact of the matter is, there are a lot of as-holes, out there... of every color.
