So this guy in my BJJ class tries to act like a bit of a know it all. A few of my classmates have come to me and said that people get on his nerve. He seems like a very rushed guy and sounds like he has a lot of anxiety but comes across as arrogant and aggressive. We will call him Sam.

I was talking to my mate about Judo and was saying to him "Yeah they say Judo gives more injuries than BJJ so that's why I'm not doing it" and then Sam chimes in and says "Obviously! You get more injuries in Judo than Bjj since you are throwing people around!" We just looked at him and ignored him. Then my mate continued on with what he was going to say.

There have been a couple of more examples like this. But I was wondering what the best way to deal with this guy is? Simply ignore him?
