no, you're not rating it, you're just heavily implying that it isn't legit. when you ask what kind of a brown belt gets tapped out in 38 seconds, you're mocking his brown belt. don't try to back paddle now, you posted several times in this thread and all of your contributions reek of ignorance.
getting choked by diaz does not mean you aren't a brown belt. getting tapped by duffy when you were a purple belt does not mean that you can't be a brown belt now.
the fact that you would sit in your chair, having never trained a single second of your life, and mock pro fighters and their ranks in BJJ is fucking hysterical. go to a gym, buy a gi, give bjj a try. it's great fun, you'll get in shape, you'll learn how to defend yourself, and you'll likely meet really cool people. there is absolutely nothing holding you back, bjj is not like boxing where you'll get your face all bashed up, you don't have to be a tough guy and it caters to all types of people. and to top it all, you'll get some perspective on how much of an absolute fucking twat you sound like in threads like this one.
