No. I do not post in every thread. I've avoided threads involving abortions, homosexual marriages, contraception, and other topics that have been previously posted on this board. I simply do not have the time to consistently post on this message board.
Also, I am interpreting your casual manner of bringing up pornography as a presupposition of the issue's amorality. If I were to ask the question, which tax accountant in town do you go to in order to cheat on your taxes? I am automatically assuming that there are tax accountants that help cheat on taxes, and that I am speaking to an audience that treats the act of cheating on taxes in an amoral manner, one in which the act can be spoken of freely.
This thread promotes the use of pornography. It is logical to assume that you would promote something that you deemed moral, or at the least amoral.
