If you want to play the music you want to play than do so, and don't let anyone stop you. In my experience, the only thing that gets...bothersome is the ego...but that shouldn't stop you. Regardless of whether a player you are playing with has a good or bad attitude, or a solidified opinion on their good (or bad as the case may be) techniques, you can always learn what to do and what not to do. Everything including guitar and who you play with is trial and error.
