Saints players and other key sports and public figures are angry at Drew Brees for his anthem comments

I have a question that maybe a person of color could answer. Why does the knee need to happen during the national anthem? Is there no other time that it would be possible without drawing the ire of the patriots around the country? I am not making light of the cause of BLM by asking this . I just want to know why its important to insult the flag and country for the cause. Help me understand.

The same reason these guys didn't decide to do this during warm ups or something? (And what Housecall posted...)
