Greed, lust, and fear.
American liberals literally want to...
1) own and control it all
2) feed their Luciferian appetites without hindrance or shame
3) remove as many people from the world's population as necessary who stand in the way of 1 and 2.
This is what I have learned about the fundamental nature of the liberal, one world, globalist agenda presently destroying not only America but the whole planet.
Sadly, the conservative agenda isn't terribly different except it isn't as nefarious.
