Why do people feel entitled to judge the name I pick for my baby?

I hate when people state their opinions on names that's why I just don't talk about the naming or ask anyone. the hate is real. I don't go around talking about how ugly your name is or saying any of that too your face why is it different with the naming of my little pumpkin? I also have people ask me a lot and had a coworker ask me every day I worked with her if I came up with a name yet like no it doesn't always work that way!! jeeze.
