I don't blame the Antifa supporters tbh, that country (United States) is such a joke that I'm surprised there isn't a total violent uprising.
No shade.
You're witnessing the rumblings of a violent uprising. Best believe that. What we're seeing in the NFL is essentially a modern day slave rebellion. It's only going to get uglier as the people (black people, principally) become more defiant of Trump, supporters, and the cowards on the left who want to compromise with these fascists.
I PUT 'RESIST' UNDER MY AVATAR!
I'M DOING ALL I CAN!
Also: Players being paid tens of millions of dollars per year are slaves?

Black bodies exploited by a system that is one of the only few avenues of wealth in the black community, where they're appreciated for their athleticism and only discriminated against when they speak their mind against the dominant society? Sure sounds like slavery. Millions without actual freedom are meaningless.
I dont think I have ever said this, and hope to never say it again, but Eminem distilled this issue pretty well, its simply athletes using their platform and voice to speak up for those that lack one. Like black athletes have done in the past. Personally I think the slave analogy is a little bit of a reach and actually gets away from the message many have written about or expressed.
Though if people like ole tummyfat are struggling to grasp the simplicity and straightforwardness of their underlying message, slave stuff aside, that is a failure on their part, no one elses. If they object still after understanding the message, or demand they view the flag through their personal interpretation and symbolism, that just helps prove the athletes point further.
