No. This is being overblown.
Here is the relevant language.
The specific acts being listed are only applicable to (b). That provision has to do with what counts as taunting another player. So, for instance, if you spin the ball at an opposing player's feet, it could count as taunting. If you just spin the ball in the end zone in general then it's fine. If you flex your muscles directly at a quarterback you just sacked, that could count as taunting. If you just taunt towards the crowd or to your teammates, you're fine.
