Would twooffour actually being a parent have really changed whether his thoughts on the idea of refusing to allow your children to see things based on your opinion of them are valid or not? Whether he's actually a parent I think is irrelevant, for this particular situation at least.
His overly-lengthy and mostly condescending tone aside, I agree with twooffour. Shielding your kids from certain movies and shows just because you don't like them is just completely absurd.
