Colin is one of the worst qbs in the league. It's not "dat cism" it's the controversy he brings outweighing the benefit of having him on the team. He is absolutely a flawed qb. He has been positively attrocious the past few years. Even when he was playing in a system that worked for him, he was a one read and go guy who absolutely never learned how to read a defense.
This play drew a ton of attention, because the defense didn't even bother disgusting, they read Colin and the corner literally stacked on the line knowing he wouldn't see him. Torrey was jumping around screaming to let Colin know and he STILL didn't see it. Ended up running the ball right into a stacked line. The whole anthem thing is stupid and the NFL is full of racist rich white dudes, but again, his talent to controversy ratio is the deciding factor here just like what happened to Tebow.
