If this election has taught us anything, it is that if we continually scream at and belittle adults, they will eventually ignore us. Every epithet, every word of shame-speak will then fall on deaf ears. We will find ourselves in the very position we placed them in: powerless and irrelevant.
You should be asking yourself: Why was the birther and the racial element so prominent during the Obama years? These things do not happen in a vacuum. They have a root cause, and it is not, as you might conclude, because every Trump voter is a racist, a bigot, or stupid. Think more deeply.
I might also add that by pigeon-holing the entire body who elected Trump into the category of ignorant racist bigots, you are committing the very act of stereo-typing you are decrying. You are discrediting yourself by accusing people of things they know they are not guilty of, and reinforcing your own irrelevance. If empathy is your concern, perhaps you should start with your own.
