Left, center and right culture exists even within libertarian circles and it will necessarily spill over into politics sometimes unfortunately. Hopefully we can avoid the clashes as much as possible by not dodging questions of ideological consistency, which we need, but without strawmanning and further perpetuating the divide.
I recently joined r/CenterLibertarians. It's a small sub that l hope will grow, as an alternative to the already well established culture-specific subs. But I try to even visit r/Donald from time to time, just to get a look inside another cultural bubble and try to understand their perspective better.
People are better of when we talk with eachother, rather than just bumping heads in the voting booth or on the battlefield.
