Do you really think that no one has suffered for having conversations pro gay rights, civil rights, gender equality, and all those other previously inadmissible topics? No, they spoke publicly, and paid the (unfortunate) consequences of the day ... but they carried on because it was the right thing to do.
What exactly is it that we're trying to "express ourselves" about here? what "progress" are we trying to make on old men having sex with young girls?
If there's change to be made, then someone is going to have to weather the cultural storm that speaking out about it brings in order to bring change. If it's not worth weathering that storm, then maybe it's not worth having that discussion in the first place.
