There's no argument. You decide if it's an appropriate attribution or not. If it's not, they're in violation of your copyright, period.
I agree with the parent that someone who is going to steal your content, is going to do it regardless of the license.
And, remember: if you don't actually register your works with the Copyright Office, you can't sue for damages. All you can do is get them to take it down.
