Hanlon's Razor: "Never attribute to malice that which can be adequately explained by stupidity." Sturgeon's Law: "Ninety percent of everything is crap."
I found the thread somewhat juvenile in the beginning. I've worked out with judoka in the past. They had trouble throwing me since I used extension and they could not enter. Then they'd try to sweep my feet and I'd just extend and life up my foot. I let them throw me and then reach up and tug their gi and toss them over (usually off balance do to a sacrifice throw).
Does that make them bad or me good. Neither. These were not street situations and stylistic differences explain the dynamics. I think the guys on the site have a bit too much testosterone and too little experience with martial arts.
