As an HR professional, that’s just incredibly hurtful to read. I’m really sorry you had that experience, which is making you generalize a whole a set of people based on what they are working on. And it’s also bad to see a lot of people just jumped on the hate train and upvoted it.
This level of armchair negativity contributes nothing to the conversation.
I was not expecting to change your opinion instantly. I’m sure you have real experiences backing up your sentiments.
Still I hope you get this same feedback from other places, and realize that the world is usually not black and white, bad and good… and you’re actually welcomed to develop more sophisticated views of things and people around you.
It’s all easy and cozy to think in extremes, but it will get you nowhere as a person.
