Some liberals do that. When you decide and say that "liberals do that", you're choosing to be divisive. You're saying, effectively, that liberals are one camp and conservatives are another, and that all liberals are the same. America is made up of 300 million kinds of people, but it's one country, one spectrum of many viewpoints. Not sure how you can be smart enough to make the memes you make, but believe that polarization/antagonism is the best choice for any individual to make. How does it help?
