Re: Sports fans. I'd say it depends on the sport. MLB fans in general would be more right-leaning, but NBA fans would be more left-leaning for example.
Re: This site. I'd say it's moderate-right overall, but comes off as more right-wing simply because the most right-leaning posters don't seem to have much more going on in their lives besides showing off their R credentials, so they flood the place with "stupid progressives" tidbits. And with a lot of those being legit stupid progressives, it's the sort of stuff that the more moderate people either don't respond to or have to agree is stupid. I mean, I'm sure I could throw up a bunch of random links or tweets about stupid racists or dipshit right-wingers, but I actually have stuff going on in my life and have better things to do with it than search out that stuff and post it with the usual "TOLERANT left" or "they are the real enemy!" dipshittery that those people do.
