A .xxx tld would be the beginning of massive censorship on the internet
In the past senators Max Baucus (D., Montana) and Mark Pryor (D., Arkansas) have already proposed to make the use of a .xxx domain mandatory for adult content. Stuart Lawley of the ICM registry has already stated that if the .xxx tld is approved they will start lobbying to make it mandatory.
This opens a huge can of worms. What exactly is adult content? Hardcore Pr0n? Sites about breast cancer? Sex ed sites? A youtube video of women wearing bikinis?
Who gets to decide which sites can still use a .com domain and which sites will be forced to move into the .xxx ghetto? What about the owners of adult websites who have invested thousands of dollars into building a brand? What about their SE rankings? Do you really want to put thousands of people out of business simply because you don't like the product they are selling? Well, what if some Islamic extremist started closing down websites he didn't like? Or what if some extreme right Christian sect decided all sites about the theory of evolution are inappropriate?
And who will pay for all that? Surely policing the internet to make sure no one secretly put up some adult content on a .com domain would come at a cost. Do we raise the price of .com domains to pay for some new government agency to police the .com tld?
If you allow the creation of a .xxx tld and as a result the eventual mandatory segmentation of the internet based on content, you'll wake up one day in a world where the internet will no longer be the 'ultimate free press'.

If you believe in freedom of thought, freedom of speech, than don't keep silent.
