As I've said... I don't get offended at that when it happens to me. If I'm not sure of an answer, I'm not going to look it up or tell you to look it up, I'm going to leave it alone and wait for them to either find the answer themselves or have someone else answer it. This place isn't a google search.
You are free to answer every question you like, just like I'm free to ignore questions that I'm not 100% sure of that would be easy to find the answer to. I'm sick of doing the research for other people, to be honest. Having to post tens of links explaining why something is canon or not did that to me.
