BUT... open relationships are as paleo as you can get.

In Italy it's quite normal to eat raw or boiled vegetables dipped in olive oil - "a pinzimonio". I think I do recall eating a raw artichoke this way. I'll make a trip to the organic shop and try it out.

Converting someone is nearly impossible, because one's mind will always be able to find motivations to justify whichever their alignment is.

Things like "Cooking helped humans make a big evolutionary leap" and "Cavemen died at 30" are just examples of what one's can come up with to justify anti RPD positions.

Not to mention that it's humiliating. I feel like a door-to-door salesman if I try to make my mother drink wine instead of beer at a restaurant. Even if I succeed, it won't stick.

I think I'll just let facts speak for themselves.
My parents know I eat raw meat (and they tell everyone, describing me as the weird relative of the family), so my only hope is that while their health keeps deteriorating and mine improving, they might one day become desperate enough to try out a paleo, if not raw, diet.
And if they won't... fine, it's their choice to feel miserable all the time and eat addicting food rather than feeling healthy and eating real food.

Anyhow, I wouldn't date a vegan... spending time getting attached to somebody who is prone to extremism and political brainwashing, never mind that with my diet I'm already vegan Satan, sounds like the recipe for disaster.
