According galvestonhorn's post (as interpreted by bystander) racism has always been a problem (bystander's interpretation) and it is ridiculous for football players to think that they can change that (galvestonhorn's post). Those two together indicate that those two posters concede racism currently exists. I agree with them on that much, at least.
I, for one, am not saying it doesn't exist to some degree.
I personally believe the attention, activity, anger, drama, expression, and rhetoric does not remotely match the level to which this is actually an issue....and that is why there is so much push back.
