In order to not derail another thread --
There's no good reason for polyamory to somehow be made into
a movement, & in fact I've gone on record speaking against "activists" who make such noises.
Likely outfall: Monogamists use this as a rallying point to revitalize monogamy by stirring up the 98% of the population that's stuck with it -- much as the Weird Right has convinced "po' white trash" that their lives suck only because they're being actively discriminated against by everyone who's not "po' white trash." Every inherent problem with monogamy can then be blamed on us subversives; certainly, most vees & "open couples" will shelter on the Monogamist side.
People attempting to practice nonmonogamy in their life should focus on learning HOW to best practice nonmonogamy. Once everyone has a grasp on that, I'm certain the tree-hugger stuff (peace, harmony, unity, brotherhood, free healthcare, universal education...) will fall into place.
I hope you're not suggesting that everyone involved in poly-amorous relationships has to fall on the "left" side of the contrived political spectrum. Personally, I grew up "po' white trash" and part of that has stuck with me even though I've moved up in the world.
I've never really understood how a particular relationship style is expected to dictate a person's politics as well. It would seem logical that lesbians (how I have generally identified myself) would be able to come together to stand for their rights and ignore their other non-related political beliefs while they are together in common cause.
I hope you're not suggesting you're so naive as to be unaware of how "I hope you're not..." is a passive-aggressive gambit...?
Firstly, it helps to do research, even the teensiest little bit.
Of course, many Wingnuts might make the case that
The American Conservative is a Pinko LibRuhl Lying Mainstream Media rag, but here's an op/ed on "White Plight" & some similar articles:
"The Invisible Poverty of 'Poor White Trash'"
Anyway, what would Righty Utopia look like? A free gun for every citizen? (No free food, of course, because THAT is Socialism!!) Evangelical preachers at "advisory" positions running every court & public office, approving all films & TV shows?
Yes, polyamory is biased toward Lefty liberal Commie Socialism. In part because modern Rightist "individualism" is actually authoritarian & even dictatorial, which don't align at all well with the ACTUAL individualist. The Leftward fit is not great, but veryVERY few people are able to embrace anarchism or voluntary communalism so that's where they run out of steam.
To put it another way, it's not that Leftist sentiments are
better soil for polyamory, so much as that it's
somewhat less bad than the self-delusion required by today's Rightism.
People who find authoritarianism sexy ought to stick with closed threesomes or polyfidelity or communalism. My bias is that those who don't LOVE obeying commands from Big Mommy/Daddy or the Supreme Council will actively dislike such control as they are forced to notice -- there's really not any "take it or leave it" fence-sitting.
My experience since 1986 is that Lefties can work well with people possessing a wide range of beliefs with which they don't personally agree. On the other hand, mention casually to a Trumpanista that I voted for Bernie in the primaries, & within two minutes they're getting in my face (literally), waving a finger at me, telling me I'm unpatriotic & probably have black friends, & more than once shouting at me.
Once again, the GOP has control of the White House AND the House of Representatives AND the Senate AND the Supreme Court AND 34 of the Governor seats... & once again THEY CAN"T DO SHIT ABOUT SHIT.
And the Wingnut peons blame "Democrats" for this gross ineptitude.
Why? Because
that's what Fox News & Facebook tell them to believe.
Rightists have had the brains bred right out of 'em, like turkeys, which Ben Franklin once admired for their wiliness & cunning.
Polyamory (as a practice) is NOT friendly to the stupid, the self-blinded, the gullible. QED.
