The Religious Right

I'm a bit confused by something, and I would appreciate it if somebody could help me out here.  First, a caveat.  I'm not a Christian, but having once been in a Christianity-based cult, I know a little bit about the Christian bible. 

I would like to know how the Religious Right reconcile their views on Health Care Reform and Social programs with the following passage, taken verbatim and completely in context, from the Christian bible. 

Matthew 25:31-46 (New International Version)

The Sheep and the Goats
31"When the Son of Man comes in his glory, and all the angels with him, he will sit on his throne in heavenly glory. 32All the nations will be gathered before him, and he will separate the people one from another as a shepherd separates the sheep from the goats. 33He will put the sheep on his right and the goats on his left.
34"Then the King will say to those on his right, 'Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. 35For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.'

37"Then the righteous will answer him, 'Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38When did we see you a stranger and invite you in, or needing clothes and clothe you? 39When did we see you sick or in prison and go to visit you?'

40"The King will reply, 'I tell you the truth, whatever you did for one of the least of these brothers of mine, you did for me.'

41"Then he will say to those on his left, 'Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. 42For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, 43I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.'

44"They also will answer, 'Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?'

45"He will reply, 'I tell you the truth, whatever you did not do for one of the least of these, you did not do for me.'

46"Then they will go away to eternal punishment, but the righteous to eternal life."

The cult didn't pay much attention to Matthew 25, but I did.  I would like to know how the Jesus depicted here and in many other parts of the bible reconciles with the "Why should I give up what I have for somebody else?" views we've been hearing?

Then, a final footnote.  The Health Care bill is carefully crafted to not take away from you what you may already have, but only to offer a choice to those that currently have none.  In other words, the poor.  How does somebody oppose this and call themselves a "Christian"?  Is fighting science and oppressing homosexuals somehow more important than this?  That's not what I read in my bible*.

Discuss.
