Way to make a [censored] generalization. A lot of us who do not want it did not only play 1 TES title. Hell, I've played all of them, save for the spinoffs, and I'm quite sick of it. Morrowind only gets a free pass because you are coming off a boat, without any prison cells or bars, and you sign yourself up in the census, as though you were a citizen. Arena has an excuse, in that Jagar Tharn imprisoned you because he knew you'd screw things up, and in Daggerfall you were on a ship (that wasn't a prison ship) that was wrecked and you ended up in a cave. Oblivion has no real excuse other than some silly ass pull.
The only title in this series that truly allows one to make up their past is Daggerfall and somewhat with Morrowind. Oblivion has you as a [censored] convict from the get go and reinforces that, and Arena was a pretty linear game anyway. There is only so many times I have to ass pull "I was caught doing a silly crime," or "I was framed!"
