There are exceptions to every rule. I do think that said genre can play a factor as well. Guess I fit in a nice stereotype. This, according to people I have and do play with.
I play rock/metal (whatever you want to label it). I am a very extroverted person. I say whats on my mind even if it means pissing people off. I am told I hit very hard. I swear like a trucker without reguard for those in audible distance. When I was on the road back in my 20's, I wrecked hotel rooms ( I know, stupid cliche), drank like a fish, did copious amounts of drugs, had unprotected sex with any woman who was willing. Actually, I'm surprised nothing really bad happened to me? Anyhow, I do believe in my case being crazy is synonymous with my instrument of choice. I have no regrets. I experienced things millions of people could have only wished for. They have to read books and watch documentaries to "get it". I am a bit calmer now. Married, no drugs. Still abrasive, loud and opinionated.
