I think it depends on what they say. If it’s not their style or a tame insult, whatever. I know not everyone likes the same names. But I guess if I had kids and someone blatantly told me they thought my child had an ugly, horrid name, I might take offense. I like to be honest around here and I’d expect the same from everyone else. But for the most part it wouldn’t stop me from using a name I love. Then again the names I like are all pretty “normal” names, although maybe not super popular. They’re also spelled “correctly” or an accepted alternative (such as [name]Elliott[/name]). So I think a lot of my names probably just won’t be someone’s style, and that’s totally fine!
I like to tell people that I’m just a random internet stranger so don’t take my opinions too personally - I like to also follow that myself. I think it’s a little different though with people [name]IRL[/name] vs. online so this is why I might not reveal names (or at least a final name) until the baby is born. [name]Kinda[/name] hard to say you don’t like the name when you see the cute little baby (unless it’s REALLY terrible, lol). I have friends with TOTALLY different naming styles, so they might not like my names. [name]One[/name] has a [name]Kaeden[/name] (made up and alternative spelling, not my style but it’s her kid, not mine) and another loves names like [name]River[/name] and [name]Lake[/name] (word names, again not my style!). Everyone is going to have an opinion.
I should also mention I don’t have kids so this view may change a little when I actually have a child with a name I love. I’d probably take more offense then but it also depends on who it comes from and what is said about it.
