Liberals don't understand the results of their actions. Ideas have consequences. Liberals hear what they want to hear. When Liberals get caught in an argument, they go and change the topic subtly.
Liberals actually think they're helping when they sign death certificates.
They don't care about outcome. They're completely ideologically committed to concepts that are destructive. Liberals worship the First Amendment instead of He who gave us those rights. Liberals typically say that they want to achieve equality for everyone. They want to make jail as nice as possible.
