Grizz, I don't think there's any way to prevent people from posting their beliefs. Sometimes, people behave online in ways that they would NEVER act out in Real Life.
For the most part, I pity people who have such empty lives and scroll past their posts - one exception to this was just moments ago when someone responded to a post that was almost 10 years old about how Zionists were somehow responsible for this person's childhood molestation experiences. I did respond to that because it was intended to incite rage, and I'm not biting that bait, this morning.
So..........try to think of those annoying posts as Online White Noise..........
