"Do your own research" is just code for "I don't have a valid source and I don't feel like looking for one so you do it."

Damn straight. I was attracted to the ideas of the Skeptic community when I was a teen. And as this all unraveled and better, more informative, and equally entertaining leftists got me hooked - I've learned to patch up these bad behaviors. Now if I want to make a point, I'll link to a source that echoes that point. Now I can still be wrong, but if I am then the person I'm arguing with has a chance to challenge the rhetoric that has convinced me.
