The point is, if you're going to make not only highly charged, but basically, incredibly insulting assertions about a very large group of people (that also happens to be much weaker than yourself) -- especially assertions that are readily seen to be based on flawed selection biases and other sloppy reasoning -- then you had better make at least the numerical parts of your claims instantly verifiable from the sources you cite.

It's just as in academic research -- yeah, maybe it's buried in the source somewhere, but no one has time to parse paragraphs, and divide numbers for you -- especially when you're already trying their patience by making such structurally weak arguments in the first place.

Pointing fingers (and, implicitly, accusing people of being lazy or unable to read) to distract from the fact that don't seem to have an answer for their main criticisms of your "argument" doesn't help, either. It's just grasping at straws.
