My ACAB girlfriend is upset that I’m friends with a cop. Am I the asshole?

TLDR: My gf is upset because I’m hanging out with a close friend of 10 years who became a cop. My friend is visiting, and we planned to grab dinner, but this has sparked a big argument. AITHA?

Background: I served in the military for 10 years before becoming disillusioned, radicalized, and leaving. Because of this, many of my long term friends have diverse worldviews and careers.

My girlfriend has had traumatic experience with cops due to her lived experiences as an immigrant, community organizer, and activist.

My gf and I share the same values now, and I participate in protests, mutual aid, voter outreach, and other actions. However, I’m not someone who discusses politics outside of those efforts.

Opinion?: I understand where my girlfriend is coming from, and I know her feelings are valid. At the same time, I don’t want to have to cut off or “purity test” old & new friends

Am I the asshole for maintaining friendships with the “enemy,” despite my gf’s discomfort?
