I think Angel was referring to Conservatives as the Republican Party, which in my opinion makes him completely justified to make statements. We can have an argument about semantics, but sadly a "Social Conservative" in our society is not a Libertarian by any stretch of the imagination. If you want to use American Politics as a benchmark, a Social Liberal and Fiscal Conservative makes a Libertarian (I would personally argue that it should be Conservative Fiscally and Socially if we were using a better scale, sadly the semantics have changed). The reason for the shift in labeling, I think, is that in America, Conservative has come to mean Traditional and Liberal has come to mean Progressive. I'd say Progressive describes the Democrats fairly well (in the academic sense, not the Glenn Beck know-nothing way) and Traditional fits the Republicans perfectly.
On topic, I don't think this is a big deal. The programs are going to continue to be funded (they're not new) and many others are getting the axe. Like any social change, it takes time, we have to slowly move away from ineffective ideas and backward ways of thinking as long as they're not hugely damaging.
Abstinence only education programs are out of touch with reality, but in my opinion they're not worse than nothing. We live in the information age, it only takes a trickle of knowledge and the rest will come, they can't shelter people from the possibility of using contraceptives with the advent of the internet. I just don't think it has that huge of an impact. I am, however, willing to change my point of view if anyone has any statistics that show that they're hugely damaging.
