However, I did not commit it, I never asserted "true mystics" or anything along those lines. I in fact admitted that my choice of words was poor, and that I was having difficulty choosing a better description.
They key point is that you go around defining the word "X" in a non-conventional way to make sure that your "all X have property Y" is trivially true.
Again, I don't think I committed the "No True Scotsman" fallacy.
