I'm beginning to suspect that this is one of those times where you are being intentionally dense for comedic effect.
But I'll give you the benefit of the doubt on more time.
A. The 1st Amendment DOES NOT GUARANTEE that libraries must carry every book ever written, nor any specific books. Address this point or STFU! I'm getting tired of your bogus "legislating what is allowed" bull shit.
B. Porn filtering DOES NOT EQUAL outlawing porn. Address this point or STFU! I'm getting tired of you claiming that ANYONE has suggested porn should be outlawed.
C. Porn is considered potentially harmful. If it weren't, we wouldn't be having this discussion.
D. As for Jillian's brilliant point, it's really not that brilliant at all. It's essentially saying, don't filter porn, just fine and arrest anyone caught looking at it. Yup, that's some pretty profound logic there.
