In other words, religion is often used to explain what one does not know about/understand.
Human nature pulls toward having an answer for everything, even when the answer doesn't make sense.
(the way many people justify voting for Trump, "to shake things up in D.C." tho he was shown to be incompetant and dishonest).
He's right; the SYMBOLISM of him kneeling/wearing BLM t-shirt WON'T CHANGE ANYTHING.
But as a symbol, kneeling and wearing BLM would show UNITY which leads to STRENGTH in the effort to change the way things are.
By STANDING (the opposite of kneeling) he shows his disconnect from truly understanding the issues.
It also gives the ignorant ones who don't even see a problem confidence in their misunderstanding.
If Trump calls him looking to commend him for standing, does he take the call?
