it's not necessarily ironic. maybe they didn't like how you used "grown up" to imply that children have the various bad traits you listed. which isn't a very reasonable or informative description of children.

I am sorry but you are twisting what I said there. I was meaning immature behavior which to quote the dictionary can mean "Marked by or suggesting a lack of normal maturity: silly, immature behavior."

People often tell others acting like an ass to grow up.

This has nothing to do with being an informative description of children and more to do with PG's troll post, now that is somewhat ironic :p

All those ways of insulting people are based in an ageist perspective, and one certainly can object to them.

For example, saying an asshole needs to grow up, is demeaning him by saying he is in an undesirable state (not grown up) which implies being a child is bad.
