Why wouldn't we be judged by the people we play with? The first few times I jam with someone, I'm making a judgment call as to whether or not I want to continue to play with them. Likewise, they're making the same judgment about me.
If someone I'm in a band or project with is offering me judgments about my playing, the first thing I need to do is figure out whether or not these judgments are merited. If I'm offended at their judgments, it's probably because, A) I know they're right and I don't want to admit it, or B) They're judgments are innacurate.
I had a band situation where the drummer stepped all over everyone and had absolutely no sense of control. He would double-bass till the cows came home, drown everyone out, beat the crap out of his kit, etc. I assumed that this was because he was very young, and had yet to develop a sense of dynamics. I politely mentioned that perhaps he should lighten up in certain parts, because he was drowning people out. he wouldn't listen, so I finally decided that I could no longer be in the band if he was in it. I left.
After playing with other young players (I'm 42) I started to get the feeling that MOST OF THEM lacked judgment. They had technical ability, but aesthetic judgment seemed to be completely absent. More than probably, this is due to being raised in a relativist culture and a school-system that gives gold stars to everyone for just showing up. Such a culture naturally erodes the ability to take constructive criticism.
There is no human existence without judgment. The feel-good, judgment-free world of psychologists is an illusion. A lot of times, we need to grow up and give a listen to the people around us so that we can develop our OWN sense of judgment and see whether or not their criticisms have any merit.
Most of the time, when I hear someone complain about being judged and I talk to them about it, it turns out that the person is just whining.
