Ed Feser is a known lunatic. You only need to look up his comments on same sex marriage for evidence. It says on his bio he writes from a conservative viewpoint and he is a Roman Catholic. I had a quick google and although I could find articles by him on the subject representing those viewpoints and being critical or opposed, I couldn't immediately find "lunatic" arguments. Perhaps you could point us to them?
