I hear you, and I can totally understand why that would feel off-putting and frustrating. It's a tricky situation when someone in a leadership or public-facing role starts pushing their political views, especially when they're supposed to be serving everyone in the community regardless of their beliefs. That kind of comment can definitely make people feel uncomfortable or like they're not welcome if they don't align with that viewpoint.
It sounds like you were already feeling hesitant about joining the council, and this incident kind of sealed the deal for you. That's completely valid. Your instinct to step back makes sense—you want to be part of something that feels inclusive and respectful, not something where you're worried about being judged or pressured based on your politics.
The thing is, you clearly care about your community (volunteering at the food bank, being open to helping the council), so it's not about you not wanting to contribute. It's about wanting to do that in a space where everyone's treated fairly. And that's a really reasonable boundary to have.
I'm curious though—do you think there might be other ways you could get involved that would feel better to you? Or are you pretty content stepping back from this particular group? Either way, trusting your gut on this is the right move. You don't owe anyone your time or energy, especially if the vibe doesn't feel right.
