Generally I ignore people like this, but the temptation to snark back is sometimes too strong.
Names removed to protect the ignorant:
Him: A 31 year old virgin?! No way. Those exist?!
I really hope you find what you are looking for but wow...I can't imagine there are many virgins out there.
Me: We're like wizards in Harry Potter. We have our own secret school and everything.
Him: Interesting. Is it the same school they teach you about magical sky fairies and to believe everything you read in a book written by ignorant desert tribesmen 3,000 years ago
Me: You know about the magical sky fairies? Who told?!? @_@

Note that this was a first contact message and the entirity of the conversation. If he is wise, he will now laugh and walk away. If not...he goes on my block list. I really don't get the compulsion to message people with practically zero compatibility with you just to heckle them...then again, that's probably part of why this guy has almost zero compatibility with me.
