As a childless adult, it’s my duty to be part of other people’s lives and support families by being a trusted adult (trusted by parents and kids) and be a good role model for others’ kids.
Why? Because we live in a society. Today’s kids are tomorrow’s adults. There are, unfortunately, a lot of terrible social influences out there, and parents can’t battle society alone. Young boys and girls need to learn and develop healthy relationships with men and women alike, beyond just their parents, in order to have something to model themselves after and to learn how to treat others with love and respect.
And this is especially so for singletons. A lot of the bad and warped ideas about “relationships” and even self-esteem comes from unhealthy views of romantic relationships. Ideas like if you’re not good enough if you don’t have a boyfriend/girlfriend. Or ideas that men and women cannot “only” be friends (objectification of other sex). Ideas that men are owed relationships and sex by women (incels). Ideas that it’s better to be with a bad partner than to be single (abuse).
Parents can’t fight all of that on their own.
While I’m less hostile to the idea (actually, I kind of like it), ultimately it doesn’t make sense. Our geographic difference makes our situation very different from EU member states. Our resources and outputs are very different, our location and geography makes transport needs very different. Deals that make sense for us among the Americas would make no sense for the EU. And the EU isn’t just trade, free flow of citizens makes no sense in this context, either.
Brexit was dumb for them, but it doesn’t mean joining would be smart for us. We should be just be allies with the EU and have lots of friendly policies, yes.
To put it another way, just because you break up with a long time partner who became abusive, it doesn’t mean you should start dating the (long distance) friend who supported you through it. Sometimes you should just be friends, for the better.
