I don't know about sickening me, cause they are helping people usually, but I definitely agree that virtue signaling is super annoying. And when its nonvolunteer stuff (i.e. parroting what some professor said/acting like your classmates are completely outrageous for complaining about valid things) thats when it gets really annoying to me. I try not to let my own opinions slip out because they are quite different, but sometimes I slip, and have to endure a couple minutes of 'rationalizing' about how what I said wasn't valid because my school couldn't possibly do anything bad. Smile and nod, guys, smile and nod, just remember that up and down doesn't always mean yes.
But I guess its part of my nature too, I believe there are places out there that will treat you well and with respect, so I suppose I am an eternal optimist. I know they exist, I have been to Costco. Just got to find the Costco of medical school instead of the walmarts.
