Likely not, though there are always exceptions.

Friends for sure. The big difference to me, between dating and being friends, is the level of physical intimacy and sexual attraction between the people in the relationship – and ideally, you want that to be a strong enough bond that you can rely on each other for those needs almost exclusively. I can’t realistically picture such a bond with a non binary person, similar to how I don’t think such a bond can be as exclusive/strong with someone who is ‘gender fluid’ (as it’d feel like I’d never live up to the expectations of a partner that wanted to physically/materially play around with both men and women, seeing as I’m just one of the two). I also find myself more attracted to certain generally more feminine characteristics, which would likely not work out well if the other person is non-binary – I wouldn’t want someone I cared about, changing/masking who they are, just for my benefit, so I wouldn’t want to put them into that sort of dilemma by pursuing a relationship.

There’s nothing wrong with being non-binary. There’s also nothing wrong with not being attracted to non-binary people.

Then again, my viewpoint has resulted in me being a single middle aged person with no real immediate family, and few close friends (they tend to go ‘poof’ once they find a wife/husband and start families). So being somewhat mindful of these things, may have negative results in the long run for most cis-folks. May be better to just hook up with anything with a pulse, and try to get some kids/connections by any means, if you don’t want to die alone. Throw every relationship at the wall and see what sticks – any hole’s a goal.
