that girl bites like a wolf

If you think "children should not be allowed in this space," you HAVE TO reckon with the fact that you are now excluding parents (and very often women specifically) who don't have access to childcare. You are isolating people who are poor, or rural, or single parents, or any number of other factors that might prevent someone from having on-demand childcare. You are cutting them off from being able to exist in public. You are denying parents and children the ability to fully participate in society.

My mom spent several years only leaving the house to buy groceries or take me to school, and even then, people would still come up to her to complain TO HER FACE about how she shouldn't bring a crying toddler to Walmart. Entitled strangers would literally try and demand that my mom leave and come back without the kids.

"Why can't your husband watch them?" Because he was at work, usually working extreme amounts of overtime so we didn't get evicted, because landlords don't like it when you stop paying rent.

"Why can't you send them to daycare?" Because that costs money.

"Why can't your teenager stay home with them and babysit?" Because I also deserved to be able to leave the house for something other than school, and taking me to the grocery store was how my mom taught me to manage a household budget, shop sales, and meal plan.

"Don't bring your kid in public if you can't CONTROL them and make them stop crying!" Kids cry when they're upset, and being dragged around a store is upsetting! Don't be an asshole! Children are human beings who are still learning how the world works, and they don't have a lot of agency. You'd cry, too.

"Spank them until they learn to stop crying!" That's just straight-up child abuse, Jesus Christ.

I have blocked multiple people who went on tirades about how I'm a "horrible breeder" who is "contributing to overpopulation" and how I and my "spawn" deserve to be trapped at home. (I am infertile and my foster kid is an adult now, so I don't know what breeding and spawn they think they're talking about.)

One person asked if I was posting ragebait for fun because "this isn't a real issue." Several have asked if this "really happens" and told me that my "experience isn't universal." (There are multiple parents in the comments who have agreed with me and talked about how hard it is to navigate the world with their kids.)

Children are an oppressed class who are treated like absolute vermin. Parents are given absolutely no support in caring for them. Good parents are set at a disadvantage even when they have all the best intentions, struggling parents aren't given resources to improve their situation or get community assistance, and blatantly abusive parents don't get caught because hitting and screaming and controlling are considered perfectly normal ways to treat a child. Communities would rather shut kids away where they can be ignored and forgotten and mistreated, all for the sin of "being annoying in public."

Youth liberation is vital, regardless of whether you, personally, like kids. You cannot ban children from public. You cannot shut children away in isolation and expect them to grow into happy, healthy, well-adjusted adults who can function in our society. You do not get to demand children be removed from every corner of public life all for your personal comfort.
