"Working parents who put their kids in daycare" admittedly may be an issue worth addressing, but it would be better to address the fact that so many parents need to have both parents working in order to make ends meet. Most don't have the option of letting one stay home full-time. And the economic policies most responsible for creating this situation have been implemented by conservative Republican administrations.
"The teaching of evolution in the schools" is most certainly NOT a problem. In the first place, most schools skip over it so gently that it's hardly dealt with at all. In the second, even if it's an unpleasant fact for some (and I honestly don't see why it should be), it IS a fact, so it needs to be taught as such. The fact that some of these unstable kids have issues with it is a problem, and that problem is caused by the cognitive dissonance of having to deal with the reality of evolution when their trusted fundie elders keep shoveling their minds full of nonsense that contradicts it and telling them that they'll burn for eternity if they ever let themselves slip in their belief. THAT is where the problem lies where the evolution issue (superficially) overlaps the gun-toting maniac issue.
The "working mothers who take birth control pills" bit is nothing but a bizarre, nonsensical, and meaningless red herring. But I note that it's the second time in the sentence that he has indirectly condemned parents for having jobs. What the heck does he want them to do -- go on the dole so that they can raise their children full time?
"Guns have little or nothing to do with juvenile violence" is absurd in the extreme. Nobody claims that guns are a cause of violence. But guns are the most common (and most effective) method of perpetrating that violence. They're just a tool, and the availability of that tool is what makes a homicidal maniac suddenly a lot more dangerous than he would be if he were limited to fists and knives.
The actual cause of the violence is varied. Some of it is simply due to mental illness, and very little can be done to head it off with certainty when that's the case. But some other contributing causes, such as relentless bullying by certain students (and endorsement of same by the school's allegedly adult administration), are already well established and are what schools ought to be cracking down on. Instead, inexplicably, they are cracking down that much more heavily on those who are already the victims of the bullying, and thus they are turning up the heat on those students who are already most inclined to boil over.
