Look at example 2.5 here: http://en.wikipedia.org/wiki/Straw_man#Structure
By reducing the argument to one extreme vs. another extreme, these are strawmen arguments... very few support either extreme, so the commenter can then knock down the arguments and look reasonable saying pretty much anything.
Your argument is that the two absolutes are not the only options, which is pointing out a false dichotomy. Of course, even that's not an appropriate response, since JoeCortopassi had already pointed out the potential problems (like excessive loss of personal liberty) with absolutes.
