Is it an idea? Has such a move ever been anything other than an idea? Are such gestures meaningful or merely symbolic? Is taking a knee supportive of blacks or is a rebellion against the flag, the national anthem, representing racism?

If you take a knee does that help any black that you know? Would it not be better to act in a way that directly helps someone black, to reach out and touch them? But to do that you would need to know someone black or live within the vicinity of blacks. If that was the case then to take a knee would be superfluous.
If you’re taking a knee as an act of rebellion then what’s been achieved? Taking a knee only works if the media report on it. If it was effective then it could be done at your gate?
So are such gestures meaningful or feel-good moments for people who having nothing to do with the lives of blacks?
It seems to me that taking a knee is merely symbolic and represents a state of things where symbolism is enough, that you’ve paid your dues in the fight for justice.
What exactly is it meant to do?
