Yes, there are many topics that are very difficult to write on as their is no 'black and white' answer. It just seems though that with many writers I have read there is a serious lack of effort in their book or whatever it may be. Maybe they didn't do enough research, or check their logic, or think to respond to possible holes in their arguement.
Though I think what is worse, is someone critiquing a decent author, and that critic has no ground what so ever to refute anything and basically tosses straw man after strawman all over the place.
I can not surely write at the quality that I would hope for though something isn't right if I'm reading something and smacking my head in disbelief for what ever it may be.
