Very interesting questions, although I have a few unsolicited comments.
Usually serveys don't have default answers selected like that. It tends to bias results.
Also, for the please explain why type of boxes, they're usually attached right on the question rather than having a single one after two questions that might require further commenting. Maybe the answers are mostly the same for both cases, in which case they're free to copy and paste. But sometimes they might like to give different reasons for each, and it makes it clearer what question they are referring to in their answer. (Plus I had already forgotten what the 3rd question was after reading the 4th question).
Also, the one about dead soldiers strikes me as American specific (maybe a few other countries too). If your survey is targetted to Americans, you should say that somewhere at the top before people start the survey. Sort of similar thoughts for the T-shirt question, but I think that is a little more widely applicable.
Also, not everyone will have a T-shirt like that. Maybe generalize the question a little to "someone" rather than your T-shirt. It would definately give me a different feeling if someone else was asked to remove a T-shirt like that then being asked how I'd feel to remove a T-shirt like that, mainly because I wouldn't wear such a T-shirt. There's often a difference between what I would do, and what I feel other people should be allowed to do. Also, the way it's phrased sounds a little biased, like there's obviously a correct answer and I should answer in a way to prove a point you'd like to make, because you were probably the one with the T-shirt.
Also the last question about extremely violent movies seems more at home in the first survey than the second one. The second one seems more concerned with the war than with media violence in general. It also feels a little biased to be asking this question in the second survey, like you're trying to draw links here, but not offering the person to option to refuse that a link exists here. Like saying the war is because of violence in movies, whereas the person might feel the war was because of big business or oil, or was maybe just a ligitimate cause.
So yeah, interesting questions, but I don't really know how to answer them.
