I do not think this is how the “end” is going to turn out. The heroes responses are wrong. Jesus did not say overthrow the Roman government. He said to pay taxes. Jesus allowed himself to be murdered. When God, Jesus, and the angels come to execute the wicked, it will not matter what physical weapons humans have – spirit creatures are stronger than humans.
Recently, surviving wildfires, drought, extreme flooding, earthquakes, etc. have nothing to do with how well armed you are.
It is good to have a supply of food and water, but it is your relationship with God that will determine survival, not how wealthy you are or how many beans and bullets you have. Take reasonable precautions and speak respectfully to all.
