Which is on the level with this. I fail to see what this proves. You can't even breastfeed in public and many public libraries don't even allow the mention of gender. You think they'll allow a nipple on a billboard? The US is waaaaay behind Europe who has had nudity in public TV (with limitations, but far less restrictive than the US). I'd like to see more liberal rules on speech, but for now they'll continue to be more conservative due to various sects of people in this country.
