I understand what you're saying & I don't think there's an issue with discussing the topic(s) per se, even when the discussions get spirited. There's nothing wrong with a passionate exchange of thoughts, ideas, opinions, etc. & discussing/debating those things is what makes the exchanges interesting. It's taking things too far that cancels out the interesting factor. When folks get hateful & ugly over someone not sharing their opinions/beliefs, they've gone too far. When it gets to the point of the dead horse being beaten so much it's pulverized, it gets boring. If it's the same thing being repeated page after page in a thread by the same people, it gets old, especially when it gets ugly.
