How many times has it been said: Don't feed the trolls! Don't reward them with your attention. They write irritating, stupid things for the express purpose of evoking a response.
So when you answer them, you reward them. And I think you know it, so if they really annoy you that much you need to exercise the kind of self-control one would expect from a mature, intelligent, 60-something. I am really surprised and sorry I had to write that.
I don't want to revisit this and derail the discussion, but it's not always a matter of simply rewarding the trolls. Their own behavior is already self-gratifying (innuendo intended).
Instead, sometimes I think worthwhile ideas come out of confronting their nonsense (and it is nonsense -- I don't for a minute think most of our trolls believe everything they write or live offscreen in their screen persona). For instance, in the present instance we added sex education to the list of things we'd likely lose in school privatization. I hadn't thought of it before and it's definitely at risk if the ultra right takes over kids' education, along with science education, social awareness, and many other things the public schools do in a progressive and thoughtful manner.
