Implicit Pluralism Starring Truth Valuing Monists

Despite best efforts to spend my online time wisely, I’ve fallen back into the habit of keeping tabs on YouTube videos dabbling in ethics. Nothing new there, but it got me thinking about a string of contradictions that continues to evade participants, capped off by the frequency with which metaethical irrealists are now accused of harboring ulterior motives. This is the stuff of conspiracy-mongers, and though it's not exactly a new phenomenon, it was never this common in the past. I’ll take a stab at pinpointing why caricaturing non-realists in this way only ends up hurting the caricaturist. 

The irrealist position being reachable through uncontaminated motives should register with you regardless of whether you yourself hold the contrary position, or any other position available on the continuum. As a former robust realist turned quasi-realist, I am not here to counter the realist view as advanced by its top-tier exponents (i.e. non-YouTubers), because the relevant literature is prodigious to the point where nobody can do it justice in a single post, and because I don't take umbrage with metaethical realists who stray from wild accusations; who never ascribe ulterior motives to others.
