when the "other side" leverages something controversial, it's a crime. when "our side" leverages something controversial, it's playing to win. the hypocrisy in US politics is strong at every level.
At the risk of sounding like a preacher (as a nonreligious person) I think a lack of moral guidance in modern life is a factor. What might've been controversial in the past, the idea that morality is an individual weakness rather than a communal strength, seems to be projected through all sorts of media.
