What I don’t understand is this.
If you’re going to be all big and tough and find it in yourself to invalidate someones identity, to which you’re thinking you’re worthy of doing, why do you hide on anon?
Are you afraid that people you know will suddenly know what a prick you are? Clearly you’re hiding something, or you wouldn’t be on anon. If you think it is within your own right to tell someone they are being a “special snowflake” then show them who you are. Let them know how a “normal non-special” person functions. Explain to them why you’re allowed to tell them who they are when you don’t know anything.
But of course you’re afraid. You’re using anon on a blog site where, chances are, you know you will be ripped to shreds by people who are far more educated and intelligent, and braver, to be quite honest, then you are. But really, I don’t understand why you think your opinion even matters if you click anonymous.
