This has nothing to do with the "religious right". This is just big credit card companies testing the waters on suppressing internet content. They try it every couple of years.
Well, no. The organizations that have been hounding the credit card companies, all the way from Collective Shout to the National Center on Sexual Exploitation, are all hard right-wing religious groups.
I'm sorry you don't like hearing it, but the people you support politically are the ones pushing this shit. No amount of you not being happy about it changes it.
