There are plenty of very intelligent liberals. Most pure scientists are liberals for example. Conversely, lots of conservatives are emotional in the sense that sometimes our only response to an issue is that our guts tell us it is just plain wrong.
There are instances where liberals were not very compassionate such as when they were all in love with eugenics. There are cases where conservatives are compassionate such as when we fought communism in Vietnam even though it wasn't a direct threat to the US at that time.
Lots of thought goes into liberals' planned economies, zoning laws, UN initiatives, etc. It is flawed thinking, but thinking nevertheless.
To assume that our political enemies are a bunch of mindless emotional nutcases is underestimating them.
Lenin, Stalin, Mao, Ho Chi Minh, Pol Pot, etc. were not delicate snowflakes who imprisoned and slaughtered millions in order to create safe zones for themselves. They did not succeed merely through emotional appeals to lovers of mixed-race, transgendered puppies.
Intelligence does not equate to wisdom. That is the quality that all liberals lack. At least in my experience.
