I'm planning to extirpate my political enemies.
What does this even mean? Are you some sort of leader of a country or a judge?
I'm not a judge or a leader of a country. I'm just an ordinary person like you.
You do not have to support political parties that you don't agree with but you cannot expatriate people you disagree with politically. You can just argue with them online.
I'll just fire a machine gun at them.
You won't be able to do anything by firing off a machine gun, except for most likely go to prison. Just let this weird dream go and don't go around telling people you have political enemies or they'll think you are weird.
