About the legislation, I highly doubt it is anymore than republicans doing their best to appeal to their base.
About the actual issue - whats the big deal? The government has always and will always watch what you do; online and offline. If you actively participate in child porn then you will be arrested, not much you can say in the defence of a child molestor. If you go to off-color sites as you describe, keep it over the age of 18 and you'll be fine. The rest is posturing.
Its silly, this is all they spend their time on. Child molestors and flag burning. As if they dont have anything better to talk about.
