My main argument was that actual edition hate, from my observation, seems to be centered on 3E players who feel that WotC slighted or abandoned them.
As a 3e lover/4e hater, I actually tend to agree with you. But it might just be that I've self-selectively noticed more people who say things that agree with me and ignored the arguments from the other side, even when they were nuttily annoying too.

BTW, I don't hate the 4e players, and I don't hate the 4e designers or WOTC. I just wish they'd "let me" keep playing my game.
I realize they DO let me, but the slighted and abandoned and bullied by WOTC feelings are real, at least for me.
If the pre-4e WOTC and TSR material were available on paid PDF and the GSL allowed the same companies to produce 3e materials, particular dual stat'd adventures, most of my hate would disappear, I think.
And if they'd give Paizo the rights to Greyhawk, I'd bow down in praise!
