Here is a sentiment, often seen in Facebook comments, that does not accurately reflect libertarianism, though it is portrayed to: "As a libertarian, I don't care what he does." To clarify, this is not exactly what the libertarian qua libertarianism should say. Here is what it should say: "As a libertarian, I don't believe he should be coerced to not conduct himself in that way, on his own property or the property of another who agrees to let him do it." Just rolls of the tongue don't it?In any case, as libertarians, we are allowed to "care" about what other people do, we are allowed to have opinions on their behavior, we are allowed to make judgements about the consequences of behavior, we are allowed to shake our heads in disgust, preach against it, and so on. Libertarians don't have to refuse to make utilitarian or moral judgements about behavior just because we believe coercion is wrong.
