Most of them are not arguing against these things.  They are saying that there are better ways to help people than endless government programs.  Conservatives generally favor small government (in theory, some are not always consistent) and the government taking an ever increasing percentage of your pay check and saying "trust us" does not sit right with many people.  Jesus called people to go out and look after and support the poor ourselves because he knew the personal charity and interaction was crucial.  He did not say "lobby the Romans to hand out more loaves of bread" because the bureaucracy of government assistance is often dehumanizing to those forced to accept it.  In summary there is legitimate room for disagreement about how to best serve the needs of the poor, children, and the elderly and to denounce certain views as "evil" only because you disagree with them and without proof that they are intrinsically evil is not a good idea.
