I would really hate for this to become a parents vs non parents thing.
I don't think it is at all @HesterShaw1, and I'm sorry if it seemed like that's where I was going.
It's just something I've noticed with some of my (former) friends.
One of my oldest and dearest friends never wanted to be a parent. She's no Dementor, (but she has admitted to quite enjoying lockdown now she's used to it). But she likes children and gets them and cares about the crazy shit they like, she just doesn't want to be responsible for any.
I have a lot of friends who never had children and I always presumed that although children didn't feature much in their lives that they still accepted that they were people just like people of any age you don't have much contact with.
But it's clear to me now that they have no time for children, including mine. In retrospect there were clues I chose to ignore. But this is very much a black day of my soul. I know it's individual, or a small group dynamic.
When I was first on MN I came across the people who hate children (other than their own). And I always found it utterly bonkers.
Like if I said "Well, I love my own Mum obviously, because she's mine, but I hate all other people in their 60s." 
It's a bananas thing to say.
But mothers say stuff like that all the time on MN about children. And I know also there is the parent of younger/older children divide:
Parents of toddlers who don't want pre-teens in the play park, even though they are still kids and have nowhere else to go.
If you ask them not to use the toddler swings as a goal, IME they are super happy not to. But they are kids (people!) too and we need to make space for them.
So it's not a parent/non-parent thing at all. But I am trying to figure out why so many are so excited about performing help for "the vulnerable" whilst refusing to acknowledge the needs of one of the most vulnerable groups in any society.
I think there is a pattern, but I haven't figured it out yet. It's not whether you have children, or how you voted on Brexit, or anything so simple, but there are some patterns that will make sense of this.
