According to the article shared by The Advertiser, which originally appeared in the New York Post, I'd be considered dumb due to my current math skills (see my earlier comment in this thread for details). And according to other comments in this thread, I could be considered dumb because I've had kids.
I like anti-smoking laws. They prevent me from having to deal with second-hand smoke, which also gives my kids (and their mother) instant asthma attacks. I'm a bit perturbed that smoking is allowed in my apartment building and I can only hope that my neighbors who smoke take the necessary precautions. I should not have to be subjected to "natural selection" if they start a fire in their apartment and it consumes mine as well.
Likewise with seatbelt laws. If I crash a car into another car and someone sustains an injury that could've been prevented by using a seatbelt, I'm the one who gets protected.
As usual, these things are a little more complicated than what they seem to be on the surface. If the situation is actually one of education rather than intelligence (also see my previous comment in this thread), then part of the issue is that education isn't a high enough of a priority in this country. Often, the most crowded schools are in the poorest areas. These schools don't get the funding they need to provide education, which is little more than test training. The test scores are low and their meager funding gets cut. The system is designed to fail.
