No, not seriously.
CMT did not ban the song because of the "politics". They banned it because the explicit threat of violence against people merely for protesting cops and the flag, the putting of protesters in the same category as carjackers and robbers, and the encouraging of people to use violence against all of them, creates a clear line of liability for them.
CMT is not some Kremlin-funded bomb-throwing MAGA racket like Overthrow America Network. CMT ispart of MTV Entertainment Group, a division of Paramount, which means they have to do business with the rest of America, including its judicial system, and they don't want to be held liable for their part in whatever might happen arising from disseminating the ideas in this song.
Funny how you leapt right to BLM. Even Jason Aldean didn't go all the way there, but looks like you heard that in his message loud and clear. Looks like the song works as intended, doesn't it?
