I consider myself a pretty solid progressive, both socially and economically. Definitely to the left of most elected officials.
I live with my brother and his girlfriend.
He's progressive on some issues. Mostly economic. He's 100% on board for things like environmental and climate change advocacy, progressive job programs, taxing the rich, etc. He's closer to a centrist on social issues though. He's not racist or homophobic or anything, but every once in a while he'll say something that makes me give him the side-eye. He's gotten better though. For example, he used to use slurs "ironically," but now understands how harmful they are even when not used to directly attack someone.
His girlfriend seems to lean right a lot of the time. I mostly attribute this to her having terrible taste in YouTubers and subreddits and being highly impressionable to whoever's opinion she last heard. She's one of those people who will go ballistic if she hears Anita Sarkeesian's name, but can't articulate why she doesn't like her. "She lied about video games." Ok. But being highly impressionable, she's at least somewhat open to have her views changed. For example, she hates terms like "rape culture" and "toxic masculinity," if you talk to her about the behaviors that those two terms actually describe, she'll eventually agree that they're terrible things.
All three of us are irreligious, but my brother and I were raised Christian.
