How about this:
Maybe I don't have f*cking TIME to write a goddam article carefully guiding everybody through every piece of information or data I post, or telling them what I think about it so they can figure out more easily if they should oppose it or not based on my opinion.
When I post a chart without a caption, it's because it doesn't NEED one. I almost always post links to the original source.
I've been through this crap before, and I'm tired of it.
