Well, for your sake I would pray your white relatives don't say racist **** around you since you said you're "brown" (I presume mixed-race). But that sure as hell doesn't mean they're not saying it when you're not around.
Let me put it to you this way: I like a whole range of stuff - sneakers, streetwear, hip-hop, alt country, classic movies and radio, sports and... NASCAR. Yeah, I like watching cars going around in circles. I can explain why sometime, but my point is, I kind of float in a mess of weird completely different circles.
Now, NASCAR fans are pretty much the EXACT people we see complaining about Kaep's protests and the NIKE ad, and defending cops in all circumstances by using every defense possible ("he probably committed a crime anyway," "he should have been more compliant," "he shouldn't have been holding that phone when it looked like a gun," etc.). Now these are almost entirely white folks at these races, and increasingly older but with a smattering of 20-40 year olds there, too. When you have 60,000-120,000 similar people gathered in one place, the extremes tend to show just how extreme they are, because they think they're essentially in a "safe space" for it. So you end up seeing the confederate flags, the racist/misogynist/homophobic slogans, and the attitude that "we're all friends here, right?" It's what you see at Trump rallies, and it gets the feel of a WWE event. If you've ever been to a WWE event, everyone knows it's entertainment, but there are a few people who think it's really-real and want to see actual carnage break out. And that **** is contagious, and suddenly more and more people start to either forget or ignore the entertainment aspect and demand the carnage.
That WWE mindset, the primal mob mentality, especially in these groups of white people with some/many holding racist views is really, really dangerous, not just to random black dudes that might get harassed, chased, attacked or worse, but to our entire national fabric because it can create (and is in fact creating) a culture of fear, distrust, discord and of hate. Just like one racist white guy in an adult hockey league locker room might get some of the other 20 or so guys to think it's ok, 100 racists in a crowd of thousands will make a good number of those thousands think it's OK, and they'll do the same thing the next time they're in a big gathering like that.
What Kaep is doing is getting these people to take their attitudes away from these white "safe spaces" and bringing them into these other worlds where these views aren't accepted (like here at NT - and I'm not saying you're one of them or anything like that, but we've seen examples of it from others here in this thread already). And I think it's imperative to always say to these people "this **** doesn't fly here, go back to whatever hole you crawled out of and let the 21st century move on without you, because you obviously don't belong in it."
