Something you have to understand as well is that those crowds are a mix of supporters of different candidates, and the party is eating their own right now really. I'm not so sure that every reaction is an indication of the party of a whole. Maybe it is. My thoughts:
Cheer:
Child Labor
Hard to comment, because I honestly don't know the details. I mean, if we're talking about kids that are of working age anyway (15+), I would be interested in at least hearing the details.
Letting the Uninsured Die
Under the scenario given, that it is a guy with a good, well paying job, then I say that's on him. It shouldn't be my responsibility because he wanted to save a few bucks. How would it be right that my taxes should go up so he can save some money on a premium? It might be a little different if the guy was disabled and couldn't work, etc, or could show hardship (much like what is done to qualify for a public defender) to explain why he wasn't going to pay for a policy. But in that scenario, he decided to play Russian roulette with his own well being.
Executing "More Inmates Than Any Other Governer of Modern Times"
I don't get it. If the person on death row has exhausted all of their legal options as far as appeals, and a jury has found him guilty, what's the problem? For better or worse, that's how the legal system works. He has no obligation to let them hang around for 20 years past when all avenues of appeal have been exhausted.
Torture
I'm sort of torn on this issue. One side of me says it isn't right to do it. The other side of me says a few things:
1. The other side doesn't give a fuck. They're going to torture the shit out of our guys, drag them behind vehicles, slit their throats, etc.
2. The other side was doing this sort of thing long before waterboarding was an issue. When I say the "other side", I'm talking about pretty much any force the US has fought against in the past 20 years. They don't give a shit what we're doing, or that we're nice and won't torture them. If we're talking about waterboarding, and only waterboarding, and it saves an American life, then I'm cool with that.
Saying it's the unemployed's own damn fault.
Yes, and no. It's not up to the government to find you a job. It's not up to the government to get you technical job training. It's not up to the government to make your employer pay you $20/hr to flip burgers. But when I see signs for HELP WANTED at McDonalds, Burger King, Sonic, etc, and then I see people that live 5 miles from those places complainint about not having a job....there is some sort of disconnect. Some people simply find it easier to live off of the government teat. Would I want to work at any of the above establishments? Fuck no. But if that's the only kind of job that my skillset afforded to me, and I was unemployed, then I'm going to go flip burgers. It's a little different for those with legitimate mental or physical disabilities. I've got no problem with the government helping those folks. I just have a problem with the folks who want government money who are able, and refuse to help themselves.
Infidelity
I don't see the problem in asking that question. I want to know the character of somebody who wants to be president. If he took a really bad shit 10 years ago and somebody smelled it down the hallway, I want them to ask the guy what he had for lunch that day. When you put yourself upon that high of a platform as being a candidate for POTUS, you know you're going to have to answer some stupid questions, and clear the air on shit. Your entire life is going to go under the microscope. Honestly, I think his answer would have been more believable if he would have said something along the lines of "Look, this bitch is an ex-wife; she's fucking crazy. That's why she's an ex-wife. Schedule me a polygraph, and we'll settle this shit". Say something that Americans could relate to if it isn't true. That rant just sort of reeked of GUILT.
Boo:
Sexual harassment accusations (could also fall under cheering infidelity)
See above.
Not blaming "the whole Muslim world" and merely discussing Al Qaeda's stated motivations that extend beyond the oversimplified "they hate our freedom".
Again, I think this falls under the mixed crowd type of thing. Ron Paul is pretty much spot on. The entire muslim world doesn't hate us. Fuck, my primary physician is from Pakistan. His wife is Israeli. That makes for interesting conversation in itself, but I digress. Those two are just as Western as anybody else. We almost guarantee ourselves future problems because we go over to other countries sticking our dicks in shit where it doesn't belong in the first place. That, and lunatics preaching crazy shit to otherwise impressionable people are the problem. Generalizing the entire Muslim population is stupid.
US Soldiers who happen to be gay
Telling a soldier he can't be in the military is no different than telling somebody that is black that they can't be in because they are black. I don't have a problem with gays in the military as a general rule. A gay person in the military causing a problem by dry humping a straight soldier in a foxhole, or sticking his finger up some other guy's ass in the shower is a different problem than some dick lashing out at a gay soldier because the straight guy has a thing against gays.
Legitimate Mexican Heritage
Stupid reaction. Plain and simple.
Do unto others as you would have them do unto you
Again, Ron Paul makes sense. Some countries want to start shit just because. That's one thing. But again, we stick our dicks in alot of things we shouldn't relative to foreign policy.
