IMO, I think its a bit foolish to want to close your acct. because of what someone says on a message board, in addition to the fact that there is a very good chance that you'll never see said person. No, I'm not talking about some challenge match, I'm talking about....if for example, Terry said something that upset me, chances are, I'm not planning a trip to TX in the near future, so....I take it with a grain of salt, ignore him, and get on with my life. Its a sad day, no, a very sad day, when I let the actions of someone on an online forum, ruin my life. For the record, Terry hasn't done anything I've mentioned.

Just using that as an example.
But, in any case, to each his own. As I always say, this is the best forum I've been on. We do have ways to address issues, so if someone is not or chooses not to take advantage of those methods, then its not my fault if someone is unhappy. You can RTM the post of the offending person, put them on ignore or perhaps contact one of the mods here, via email or PM. If there is an issue, not addressing it, isn't helping the situation.
As far as people bashing videos, schools, teachers, etc....one would think that if you put someone on youtube, it'd be a quality clip. I could post something I think is the best, and 10 others can watch it and think it sucks. Thats the nature of the beast. Of course, to say that everything on YT is good, well, I think you're kidding yourself if you think that. And IMHO, that is probably the #1 reason why people look down on the arts. If someone posted a TKD clip and the people in the clip had poor stances, no power in the forms, the SD looked like garbage, the person watching is probably going to judge ALL TKD as garbage, even though there are great quality schools out there. Again, its the nature of the beast, and I think its a small issue to get riled up about. Then again, it shouldn't take much to see, especially if you've been around long enough, to see something and know whether or not is good or crappy. I take slight offense to people who post crappy Kenpo, but I also understand that I'm not a member of the Kenpo Police Dept. and there is nothing I can do about it. I shrug it off, and go about my training. There is good Kenpo out there, just like there is good TKD, good Bujinkan, good BJJ, etc. I do my part, as should everyone in their respective arts, to spread the art in a good light.
I look at it like this....I'm not trying to impress anyone with my Kenpo, Arnis or BJJ. I do those arts because I like them. If someone thinks they suck, thats fine. I have no desire to post a clip because I dont care about impressing someone or trying to prove something. What I do works for me, and thats all I care about. I know what the arts can and can't do and thats all I care about.
