I’m just wishing for a Lemmy instance where center-left and center-right folks could interact and discuss general topics, some of which may be political.

What is stopping people to interact cross instance? That is the very idea of the Fediverse to allow to interact with people from other instances.

I understand that the current opt-in federation model of Lemmy somewhat limits this, but I think a reasonably well moderated libertarian instance would be allowed to federate with lemmy.ml.

But making separate instances is very helpful in moderation and “pruning” the network to prevent an alt-right take-over as has happened with so many other non-mainstream social media.
