Instead of making baseless claims, please articulate why you think that the left is ignorant or cruel? For the life of me, I can't think of what the left has done that rises to the levels of ignorance and cruelty that the right demonstrates. For instance:
Right wing voters IGNORANTLY insist that they are the fiscally responsible ones when they consistently create bubble economies and borrow massively to give tax breaks to oligarchs, all in the name of the mythical free market. If that's not ignorant, I don't know what is. When you compound that with their absurd, religious dogma, bigotry and xenophobia and general anti-intellectualism, the question of ignorance is, literally, a no-brainer.
And what about the CRUEL way that conservatives are always finding new ways to screw the poor? Gutting the safety net, disenfranchising poor voters through voter suppression, subjecting the working class to sickness and death through environmental and industry deregulation, the list goes on and on. I can't think of a liberal policy or attitude that approaches, in cruelty, what conservatives do as a matter of course.
Now, I realize that definitions are frequently where our differences reside. Conservatives, for instance, think that it's cruel to tax the wealthy. They think it's ignorant to limit the scope of religious influence in public institutions. They think it's more wrong to call them ignorant than it is for them to do ignorant, hateful ****. I get it, you're sensitive when it comes to your own ego or wealth or god and completely callous to the humiliation, poverty or exploitation of others. You're hypocrites.
When your heart breaks for "your people", I assume you mean rich, white people. That is the problem. If you cared as much about ALL people and didn't see rest of the world as your competition for the control of minds and resources, we'd all live in a less ignorant, less cruel world.
