I used to work in one, and it wasn't good. It was very macho, very dog eat dog, and women got targeted for bullying. Women were often the butt of "jokes" and were publicly humiliated for making mistakes. Tbf a lot of it was the organisation had a toxic, bullying culture.
A lot of men would openly make nasty remarks about "moaning feminists" and how "men's rights are being destroyed by moaning women".
On the plus side, lots of men really hated it. There were many that were fiercely protective of women and hated to see them mistreated. And like I said a lot of it was the inherent nastiness of that organisation
The PUA types are hilarious as long as you don't get stuck alone with them. So easy to trigger; so easy to convert to MGTOW. ("Men Getting Triggered Over Women".)
If you're stuck alone with them, things get bad quickly. Don't let this happen.
