Can I call my son Asher?

I am in a heap of baby groups on Facebook. There was a discussion in one today about the name Ezra. Someone stated a non Jewish person could not call their son Ezra. There was an argument and the admins shut it down. They said Ezra was fine as it wasn’t like the name Asher which should only be used by Jewish people. I like to think I am pretty across these things usually. I research and work to be respectful in all aspects of my life. I’m in Australia and I know a heap of Ashers, both male and female. I’d never thought for a moment their names were inappropriate. Am I wrong? I’ve googled tonight but I find googling names really hard because you get pages and pages of baby names sites without much context. Thank you.
