I honestly see the differences between the moderate left and moderate right as almost insignificant. If a 3rd party was formed I wouldnt even be surprised.
Were running out of room to reply here. Ill just say I guess the republican side is fractured just like the left is. For instance I know a lot of liberals who are not Marxists. Id really like that 3rd party. I feel like sane people are ready to ditch the insane people.
On the subject of "enabling the suppression of their fellow man", the only really hot-button issue for Republicans that can truly be framed as them defending against their own rights being suppressed is gun control. The rest of their major issues either fall on the wrong side of suppression, or aren't really about somebody being suppressed in any direct way.
And the worst versions impute sinister motives among those implementing controls: that it's an attempt to suppress economic activity and make people slaves of the government/elites/etc.
Indeed, a May 2020 Gallup poll says that 32% believe that same-sex consensual relations are wrong and 24% of the US believe that same-sex consensual relations should be illegal. So not only do they want to be able to not hire, they want people who like the same sex to face legal consequences.
The symmetry is pretty shallow, though. If you look past the grievances about being criticized and ostracized by the other side and dig into the underlying public policy goals, it's pretty easy to spot categorical differences. When a BLM protestor talks about equal protection under law, they're referring to not getting shot by the government. When an alt-right protestor can be coaxed into listing the ways in which their legal rights are being infringed, they start bringing up stuff like the right to fire someone for being LGBTQ.
