One potential reason the guys in the channel get irritated with it, apart from them being actually sexist and therefore uncomfortable/guilty, is that your starting assumption that they WERE sexist was wrong. To have a preachy bot post nominally inspirational quotes from women, with the ostensible goal of demonstrating with child-like simplicity that women are people too, would get on my nerves for two immediate reasons: 1) I get it, I get it! How many cliches do I have to scroll past before we reach mission accomplished? 2) Someone really thinks I'm stupid. It's propaganda, but worse than that, it's propaganda with an assumed audience of evildoers to thwart -- and I'm included. I get the frustration with the male-centric dev culture and I'd fight back on that for sure, but this kind of holier-than-thou brute force attack levels a possibly undeserved accusation at everyone forced to read it, and it also flouts some of the most basic aspects of psychology in its strategy.
