Unless there was more than a "vibe" as you say, I think this is more a problem on your end. When in need of help with musculo-skeletal issues, you turn to the people with knowledge of musculo-skeletal issues. Many such people are really, really passionate about fitness. Sure, I've known gym-dudes who are exactly as dumb as they sound. But they, in my experience, don't really have the focus nor the good-will to want to actually help others with it professionally, and some more serious fitness-people I've asked for help in the past have been overjoyed to share their knowledge and were exceedingly helpful.
In summary; I think its unfair to judge him based on this "vibe" simply because you associate it with other people who belong to the same exceedingly large subculture and who have made you uncomfortable in the past.
