Anyhow, being a Oblivion fan i recall always having to defend it against MW elitest and the ignorant haters that weren't EOS fans but hated on Oblivion cause it was the cool thing to do.
Never been into creating strawman opponents as you're doing, myself. I disagreed strongly with those folks who thought Oblivion was crap because I loved Morrowind, and I didn't think much of the Daggerfall types who insisted Morrowind was a plague when the latter first came out--but fact is, offensiveness aside, they all had good personal reasons for their admittedly one-sided opinions.
Personally I like Morrowind best, but regard Oblivion and Skyrim as excellent games, each of its kind. And what's more, thanks to modding, I can make each of them the kind of game I really enjoy. Turning one against the others seems self-defeating, somehow. Who really cares that much whether X mounts a soapbox and begins shouting the virtues of a particular ES game? As long as they know what they like, that should be sufficient. It's not as though the game is going to mysteriously vanish for their hard drive if they don't proclaim its triumph across the universe, after all. You like Oblivion best? Fine with me. You prefer Skyrim? Great. Morrowind? Fantastic. Mario Bro...oh, well, now that's a bridge too far.
