Are you are questioning whether people should be issued a certificate because you are offended, or offended on behalf of a mate that was offended?
No, I'm questioning their mentality. If they can't conduct a civil conversation on here, how are they going to behave when they meet someone of opposing views in the field whilst in possession of a firearm. That worries me. Also, are they the sort of people who should be teaching our children as I'm reliably informed is what Foxdropper does.
