Why are you even asking "basic questions about biology"?

"It's not my job to educate you" is a response borne of extreme frustration with being repeatedly asked the same basic questions (that can easily be answered with Google), to the point of being suspicious that the questioner is acting in good faith. A common pattern is someone "playing innocent" in order to bait a Socratic dialogue out of someone. If you get this line often, it would be worth some self-reflection.

>If you truly believe something is true, and you believe that you have evidence to back it up, you would show that evidence every chance you get.

Meh. After being asked why I think the Earth is round for the hundredth time, with the most carefully considered answers invariably failing to convince my interlocutors, I'm now inclined to tell them to bugger off instead of wasting my energy. It's basically the fail2ban mitigation to DoS attacks.
