I have an activity class I go to, with a fair few years of experience. I'm not perfect by any stretch of the imagination, but most of the people there have a "were all learning together" mentality.

There's a newer guy there who insists on picking apart my suggestions to him (more experienced people teach newer folks) and then he critiques my form as well. The tone is not very collegial, more sexist mansplaining. It pisses me off, which makes me teary and shut down. I left class feeling like I suck at life today. Sigh.
