Romans 13
1 Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God.
2 Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves.

Politics is part of the world we live in. Refusing to participate means you are refusing to be obedient to the authority God has placed over us.
“2 Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves.”
So according to your interpretation of that scripture then the guy who turned on the gas and killed a room full Jews is not only- not guilty of anything, but is in fact committing a holy act by obeying Authority.
