Congratulations!
You've just become a victim of a conversation about politics.
Why are you a victim? The person with which you were having a conversation did not agree with you, and subsequently started to slam you because of your views. It happens all too often, all across the nation and all across the world. It is the result of people having closed minds and putting on aluminum foil caps so any opposing views just bounce off of their heads.
So maybe they don't put on aluminum foil caps, but the way they refuse to listen to what you have to say is almost equivalent. It's annoying, right? You're sitting with an acquaintance, eating lunch and discussing the latest law that addresses duck hunting. You say something they don't agree with and, all of a sudden, you are being ridiculed and told to die in a hole.
If you're reading this, and this has happened to you, I am sorry. So many people have the mentality that their point of view is correct and refuse above all costs to believe or hear anything different. They will get up in arms and shoot all kinds of ridiculous speech at you before they will ever be caught trying to understand you. When there is nothing left to shoot, they will attack your character. They might even attack your use of grammar. In defense to all of this nonsense, you should counter with kindness. That is all you can do.
If you're reading this, and you are the person on the other side of the argument with the foil cap on your head who turns a deaf ear to all dissenting views, shame on you. The whole idea of being human is interacting with other humans and finding your purpose in life. If your purpose is to seek out the humans who have other views about topics than you and to scorn them, then I think it is time for you to find a new purpose. It is 100% okay to disagree with someone. It is 100% not okay to belittle them for disagreeing with you.
We need to come together as a human race and realize that we are all different, and that is okay. After all, every conflict starts with a disagreement. If we can learn to stay level headed when someone disagrees with us, then maybe we could become a more cohesive planet.
