I'm also pretty far left, but I definitely don't really agree with claiming that struggling with empathy is inherent for men and has anything to do with testosterone. If anything, I'd say it's more that there's a societal issue with the way men are raised, but it seems pretty outlandish to imply that's just the way it is. There are also plenty of people who struggle with empathy for any number of other reasons and are still good people.
Anyway yeah as far as this thread goes, I'm definitely on the left. I'm a trans gay guy and I've seen so many people be actively hurt by far left rhetoric and the current presidency.
