You have to be blind to not see that the video is supposed to be a parody of a 50's Christmas. The VIDEO is supposed to be fun and cheesy. So, yes, I do think he's saying 'hey, it's supposed to be funny' in that regard. It's not like he'd ever do anything like this with STP.
As for everything else, the whole X-Mas thing is pretty ridiculous. There are people bashing Scott and there are people blindly defending Scott, but both parties are getting pissy at other people when they don't agree with their opinions.
On a side note, picking "Winter Wonderland" as a 'single' was a good choice considering it was one of the better ones off the album.
