Rosa Parks put her existence on the line on that fateful morning she was asked to move to the back of the bus and refused.  No cameras, no social media deals, just a line in the sand.  MLK faced water cannons, tear gas, and attack dogs when he marched for freedom.  Ghandi faced machine guns. 
That is action, one that threatens the protesters very existence, and it was epic.

The NFL took a knee during a football game.  Putting both on the same footing is very disrespectful to people who actually did something to fight racism, instead of just talking about it.

I dont care what people say.  I judge them by what the do.  NFL and all the kneeling players have done nothing significant to help this situation.

Actions, not words.
