i wrote it. and i have a BA in english from a major university. :) what i learned is that for me communication is about the end, not the means. i find "he or she" to be beyond annoying. "they" is technically wrong, but it conveys the message with the most economical clarity.
and sorry i don't use caps to start new sentences....
The use of the word "scumbag" in reference to a cheater does solve the problem.
Sure it does. They are both singular.
