Those troublesome, shaky X chromosomes!

It's easy to find lists of dumb things creationists say, and I'm familiar with that lot, but here's a fun new time-waster: Things Anti-Vaxxers Say. Here's a beautiful example of something I've rarely seen so clearly stated: they get the facts totally wrong, actually the reverse of the actual situation, but nope, that doesn't stop them from inventing a bogus rationalization around them.

You can do your own research but it comes down to chromosomes -- the X chromosome is shaky, and boys have two of them. So they are quite literally twice as likely as girls to be adversely affected by genetic and environmental factors that can lead to the development of autism -- they are at twice the risk, purely because of their gender alone.

Uh-oh. I have 22 other chromosomes besides my sex chromosomes (I've actually seen them!), and…they're all in pairs. I'm doomed.

But wait! I only have one X chromosome! I'm saved by the reduction in its pernicious influence!

Uh-oh. I've disappointed David Klinghoffer. I should probably put that on my CV. You see, the other day he praised a fellow named Tom Gilson for a post in which he provided a succinct summary of Intelligent Design creationism, and I took that summary apart, point by point. You might think, perhaps…
I was talking about sex and nothing but sex all last week in genetics, which is far less titillating than it sounds. My focus was entirely on operational genetics, that is, how autosomal inheritance vs inheritance of factors on sex chromosomes differ, and I only hinted at how sex is not inherited…
Humans appear to have a reasonable amount of diversity in their sexual orientations, in what is often referred to as "gender" and in adult behavior generally. When convenient, people will point to "genes" as the "cause" of any particular subset of th is diversity (or all of it). When convenient,…
The New York Times has declared that Academic Science Isn’t Sexist. What a relief! The authors are reporting the results of a broad study of many different parameters of the career pipeline, and are happy to report that there are no problems in academia. None at all, no sir. Our analysis reveals…

Right, the fact that men have two X chromosomes is what reduces their risk of color blindness, hemophilia, and other X-linked diseases. But at what cost????

A tiny flaw in the anti-vaxxers "argument" is that boys have an X and a Y chromosome, whereas girls have two X chromosomes. So the argument fails due to the invalid assumptions, right at the beginning.

Even if the X chromosome were in some way "shaky" (whatever that means, I can't find it anywhere in a biology textbook), then that would mean that GIRLS are at more risk.

But never let the facts get in the way of a good Scare-mongering, hey?

Once he realizes he got his X and Y crossed, I'm sure he'll find some other rationalization. When you start with Truth, evidence is whatever supports it, even when it doesn't.

The rationalisations used by anti-vaxxers are closely analogous to those used by anti-evolutionists AND the worst climate-change-deniers. Shaky premises, false "facts" and twisting away from counter-arguments.
