I generally only see that when people start spouting over-the-top things like weredragons and such. Plus, the number of people who are for it is still quite high compared to pre-release Dawnguard. Back then I remember only reading a couple posts that were "pro-werebear" and they were mostly littered with "anti-werebear" sentiments. Now it's mostly positive reactions. Maybe it being a Nord heavy DLC people are accepting it more? Where Dawnguard was a Vampire Lord/Vampire-Slayer DLC?
The last weeks I had the feeling there is more opposition to were-stuff than everything else, but that's subjective.
Maybe you're right. I guess I don't really care, as said, my stance towards the whole affair is rather neutral.
If there are werebears, I am happy for the fanst, if there are no werebears I won't even notice, I guess.
