Communities tend to attract like minded individuals. It’s not that everyone is exactly the same, but those that are very different or have very different opinions don’t generally stay for long. That said, even within those like minded individuals there’s a wide spectrum of opinions.

For me there are a handful of topics I know I’ll get down voted for sharing, because it goes against the majority. And that’s fine, it doesn’t stop me from sharing my opinion, and I don’t really mind the downvotes. I think in general though as long as you’re able to share your opinion with nuance and self awareness, and it’s not something mean or hateful people will hear you out.
