Actually, I did your work for you.
Using the "Primary Style" field in the User Profile:
Bullshido has (out of 8137 members)
156 members who list TKD
423 who list Tae Kwon Do or some varient
That's : 579 -- and MANY of those are duplicates.
(579/8137 = 7.1%)
As for Karate:
1 who lists "krotty"
286 for Karate
94 for Kenpo
88 for Kempo
Again, tones of duplicates to reach a total of: 469
(469/8137 = 5.8%)
Adding them together:
1048/8137 = 13% for Karate/TKD
Others:
515 for BJJ alone
191 for MMA
357 some form of "jitsu"
236 for Judo
98 for JKD
Total: 1397 (about 17%)
Last time I looked, 1397 was more than 1048 (which includes both TKD and Karate in some form). And yet neither is an overwhelming majority. Searches for the CMA's turn up results similar to the TKD/Karate ones.
This suggests ... Bullshido is what is claims to be. An open community where results matter more than style.
