There should be some way to preserve neutrality and not have one side find a "terms and conditions" clause to remove the opponent's viewpoint, cheered by the supporters of the opposite. It's silly politics, in the most abstract use of the word. It's like corporate politics.
It does seem like most of the hostility are in the replies to things. The one-liner quips, the arrogance, the condescending sarcasm, and the sometimes outright name-calling. It's amazing to watch how your fellow adults behave when there's no one physically in front of them.
