I think the anonymity is what makes it easier to post. There are times I have strongly disagreed with someone, and there are times that people have strongly disagreed with me. It is more comfortable to know that were I to meet any of you IRL, especially those who have vocally disagreed, that I didn’t have to feel any awkwardness, because I would be unaware. By the same token there are many posters here whom I would love to know IRL.
So I guess it’s a double-edged sword.
