I don't really have an opinion on the idea of making porn sites use the .xxx address. However, I find this little exchange interesting for the light it sheds on how email and communication in general is managed by our opponents:

ICM says the e-mails show how the National Telecommunications and Information Administration, a branch of the U.S. Department of Commerce, were subjected to intense pressure to intervene in some way on behalf of the The Family Research Council, and Focus On The Family, two religious conservative lobbyists.

NTIA members then started keeping watch as to how the .xxx proposal was reported in the media, had drafted letters protesting the .xxx domain addressed to ICANN, helped facilitate meetings between ICANN and concerned groups, and otherwise "marshaled our resources at ICANN," as one NTIA official put it in an e-mail.
