I think my reply here probably covers some of your post as well. "Bothsiderism" is an interesting term, but when it comes to relationships with people I care about who are convinced they are right, I'm willing to engage them respectfully instead of assuming they are idiots, immoral, or stupid, as I've discussed before.

I don't see it as "dangerous" because people who believe strongly enough about their views are going to do whatever they want. The only path forward I see for any chance of consensus is to have respectful dialogue, even if I don't agree with someone.

I don't think open dialogue is dangerous.

I think not having open dialogue is dangerous. I think shaming, shunning, etc people for their views before having open dialogue with them is dangerous.

This is my way, and I know it's not for everyone. Some prefer to just sever relationships and move on when people are strongly in disagreement. I prefer to respect both sides as to where they are at talk about it.
