Keep in mind that Christ walked this earth at a time when it was considered perfectly normal for people to live under oppressive, totalitarian governments. And nothing He said ever indicated that this was somehow unacceptable.
Think hard and let go of your secularist mindset.
Christians in a representative democracy are duty-bound to promote civil rulers and civil legislation based on or conforming to God's Law-Word. Discipling and baptizing the nations is not conditional upon living under despotism or tyranny. Representative government with checks and balances was birthed by Reformational Christianity. Your objection is what is truly meaningless.
Abortion, same-sex marriage, etc. are examples of rejecting God's Laws. So is refusing to obey Christ's command to disciple the nations.
