If you haven't bumped into the website Bullshido.com yet... well, you aren't missing much. They haven't found a martial art they can say anything nice about. Still, you need to listen to their criticism to a certain extent. Are they talking about you? Can you do anything to fix it? Then, let them wallow in their intense negativism by themselves.
Keep training... There's always somebody out there tougher than you -- no matter what art you choose.
BTW, you'll need to scroll down the page a bit if you get onto one of their discussion pages.
