Smash talking kids

Why is it that you can't say anything bad about kids, especially as a parent. I mean before I was completely allowed to call a kid a snot nosed brat. Can I do that now? Nope. Yesterday I ranted on FB about how annoyingly needy babies are. The mothers flipped out talking about how I need to calm down and that I shouldn't be complaining and that kids are a blessing blah blah. I get that. I didn't say I hated my baby, didn't want her, hated parenting, none of that. Just that they're annoying and needy. I think it's unfair that as a parent you can't say anything bad about kids without being deemed a shitty parent. What say you?
