I think that most people who are liberal see that some people in society are less fortunate than others, and so want to use society's resources to help them.  This means that resources and wealth need to be transfered to those who need the help and that money needs to be spent on the government departments to run such programs.

I can see the attraction of attempting to relieve suffering this way.

However, I believe that most people will be most happy if they have the most individual freedom possible and are left to pursue happiness in their own way.  That might mean following their chosen religion, or sleeping with who they want to, or facing the world as whatever gender they want to and so on.  But it also means spending their money the way they want to (ie: I prefer low taxes) and not being patronized by the government.
