My comment policy is that I reserve the right to delete any comment solely at my discretion. The main reasons I will delete comments are:
1) Gratuitous use of obscene language.Also, if you're posting anonymously you are far more likely to have your comment deleted.
2) Statements or language that I deem to be racist or sexist.
3) Comments personally criticizing other commenters.
4) Threats of violence.
5) Personal attacks which are seperate from the matters being discussed.
BUT, I do encourage disagreement. Please, if you have a problem with something I've written, I would encourage you to respond with reasoned argument. (Leo has been pretty good about this, for instance.)
I really enjoy the discussion so long as it is free of the bits above. Okay, that's enough for now.
(Sorry to have to do this, but in his three comments, the new troll who is hiding behind his anonymity has broken all 5 of those rules.)
