Yes, of course. However, I write strictly in order to earn a living. I write what I think, back it with references, and I leave it at that. I do not want people to read me because they think I have solutions to the world. i don't. And I don't want people contradicting what I say in my comments when I can see 65 holes in it. It's too much time and effort for me to continually have to respond to it. So I block.
