Honestly, I think the bullet points in that post would be incredibly popular if you polled parents as well.

Look at the 4th bullet: you think the childfree community understands how much kids need sleep more than most parents do??? I don't see how you could type that with a straight face. When you become a new parent, you get hit over the head with how important routine and sleep are for you and your kids over and over and over again. If you ask another parent for advice, the sleep schedule is like the first thing you get asked about no matter what the problem is.

That post just seems incredibly disconnected to the people its criticizing to me I'm sorry to say.
