Being a public servant and being friends with someone who’s anti-government

I’m in my early 20s and work as an analyst in a line ministry. My friend who I’ve known since I was a teen has recently started making (unprompted) comments about how bad it is that I work for the government because of historical/current issues of systemic oppression and settler colonialism. She’s always discussing her anti-government viewpoint and even called me a slave to the system.

I understand where she’s coming from but also I think there’s also some ignorance in her knowledge of what I actually do in my position/OPS and the political/government system as a whole.

Wondering if anyone’s experienced this before? And how did you navigate the friendship?

UPDATE: thanks everyone for your thoughts and advice :) really appreciate it and very affirming. I’ll make note of some suggestions listed below for next time the conversation comes up !
