not to be confused with "ethical polearmory" which is when u fight people with polearms thst have little soft baggies at the ends, sono one gets hurt :3
Yeah it's really hard to design any polearm more complex than a spear to be safe for sparring with. And even those spears are nowhere near as safe as swords like rapiers or sabres. Or even longswords.
I've sparred with large poles with bits of pool noodles stuck to the end to simulate spear tips. It's very fun and fairly safe (as long as you're extra careful with any butt strikes). But it doesn't feel anywhere near as realistic as the rapier sparring we do.
Last time I checked, that's just called polyamory. The thing where they don't know is called cheating. We don't need a qualifier pushing a conservative narrative of what love is.
I don't know I've ever heard someone say "ethical polyamory". Not sure if that's a regional thing, but for folks learning, I've usually heard just polyamorous or poly.
It's redundant within the sex positive community. Polyamory presumes you're communicating with your partners to the degree they want information and respecting established boundaries.
This is not to say there aren't relationship troubles or missteps in a complex polyamorous relationship, but that these are aired and resolved.
Adultery issues are not about illicit sexual contact, but deception.
