He seems a decent enough guy
I never got into Black Flag aside from some of the goofier songs and Rollins Band are unlistenable. But I used to listen to his spoken word stuff when I was a teen and he was pretty funny and self-deprecating. I imagine the militant straight-edge stuff only lasted a few years during his youth.
I'd rather have a conversation with Rollins than, like, Jello Biafra at any rate.
