It's ok that you don't care. I do care that people literally make things up to pretend they were attacked when they categorically weren't, irrespective of the subject.
However, genuine question to you, because this is one thing I have never understood. It does not apply to the majority of child free posters. I certainly see the discrimination they face, on a pretty bizarre basis that they have simply made a different lifestyle choice.
I don't get the fury and outrage when it is suggested a child free person, does not know what it is to have a child, when it's true...I will eleborate...
I've never been bungee jumping. I hate heights. I have nightmares that usually involve falling from a height. I know I would be petrified. I certainly know I don't want to do it. People that have done it rave about it. I don't need to do it to know I'll hate it, I already know it's not for me.
But, if someone said, you don't know the feeling you get when you bungee jump, that is true.
I can make similarities and say, I've felt the speed of a roller coaster, and hated it. I've been on vertical drop rides and hated it. I've been on high bridges and hated it. All things that have elements you could identify within bungee jumping. But I will still never know the feeling. And good, I don't want too...but it still never changes the fact I don't and won't ever know it.
So, when someone says, "you don't know the joy of having a child", there are a minority of posters who immediately jump on this weird bandwagon of "oh, so I can't feel joy then?" When it's very clear that's not what's been said at all. A child free person doesn't know the joy/stress/wonderment/horror insert whatever of having a child. And there's nothing wrong with that at all. But it doesn't change they haven't experienced it, so why the uproar when this very simple concept is pointed out? Genuine question, I would like to understand.
