Just think--if Tim Tebow had taken a knee for Antifa instead of God he might still be in the NFL. Or at least he could be a topic of conversation for people wondering why Tebow wasn't playing. I find it ironic a league that is now encouraging "celebrations" after a touchdown, frowned on Tebow offering a quick word of thanks after a score.
Offering a word of thanks certainly isn't a problem with Colin Kaepernick.
