What is the attitude of Judokas towards MMA?
As you'd expect, it varies. I'd say roughly half and half, and the younger the more likely they like it.
Considering that even with free MMA you only get a few million viewers of MMA out of 300 million Americans (about 1%), I'd say the percentage of judoka who like MMA is much higher than national average.
Probably at least half the judoka I know watch at least some MMA, and probably a quarter buy one or two UFC PPV's a year - though not many really follow it. For instance, even living in Canada, most of the judoka I know couldn't tell you who GSP is, even if they watch some MMA (what they watch tends to be random, which makes for odd conversations with them - they'll talk about some MMA fighter I've never heard of, but can't name any current UFC champs). And no, GSP is not a household name in Canada; just about every Canadian has heard of Gretzky or Crosbie, whether they watch hockey or not, but only people who follow MMA have heard of GSP.
I suspect that the Ultimate Fighter turned a lot of older (my age :icon_cry2) judoka off of MMA; most of my arguments about MMA with other judo coaches revolve around TUF antics not the sport itself. Their complaint is that it reflects badly on all combat sport; I disagree (its a reality show, what do you expect?), but that's what I hear.
The MMA fighters that are better known to judoka are (shockingly
) ex-judoka. Yoshida is probably the best known, followed by Rousey (Rousey's judo credentials are much weaker than Yoshida's, so no surprise there) - though in the USA I suspect Rousey is better known than Yoshida by a long shot, given she's American. Rousey is actually quite unpopular among judoka - see antics above. They dislike her public persona, even if they know much of it is an act.
Overall the aspect of MMA that I hear most complaints about from serious judoka (recreational folk and kids are all over the map) is the showmanship, not the combat itself (which most will admit to finding interesting and even playing around with).
And the IJF of course dislikes it (they'd probably try to ban soccer worldwide if they thought it would increase judo viewership at the Olympics), but are too busy destroying judo to really make much of a fuss over it one way or another.
