This is the same "bugaboo" about slavery being mentioned in the Bible. God didn't say we should own slaves. He was talking to Christians that did, about how to treat them if they had them. He also talked to Christian slaves on how they should serve their masters. Slavery was a fact of life, and still is in some places.
For justice and mercy, we should prefer "REAL" Christians as leaders( as opposed to pretenders), but our nations laws are not connected to God or the Bible unless through the heart of the person in government. God would and did frown on theft by taxation, but we were told to pay it if required. The point is, the Bible doesn't require taxes, it requires tithing.
Now about those pretenders. The Holy Spirit gives believers discernment. We are supposed to know that puncturing a baby's skull and sucking the brains out is wrong. We are supposed to realize that if God destroyed Sodom and Gomorrah and mentioned homosexuality was wrong about 50 times in the Bible, that He was against homosexuality. He specifically mentions adultery, fornication, lying, stealing, false gods, etc, many times. When you hear from earth worshipers, that murder babies and want to force homosexuality on you as they did in Sodom against the angels, you are required to know that person is a pretender. If they think adultery, fornication and lying is OK because everybody does it, well, you are supposed to know better. We may disagree amongst the differing denominations about some things, but I think most of us should agree that killing your baby is wrong and homosexuality is an abomination before God. They are making inroads, however, when they convince people that adultery is OK, stealing tax money is OK, and worshiping the creature rather than the creator is the way to go.
The bottom line is, if I see someone freezing and hungry, as a Christian, I should help them. There is nothing in the Bible that says I should direct them to the welfare office and keep walking. That makes government a god, and blasphemes God's Holy people. If I can tax witches and other non-believers to get help for a poor person, then what good is the church?
What will be the reaction of the Church if the pope or some other leader like Pat Robertson or Fallwell says to the flock that homo marriage is OK, or abortion is sanctioned by God? It is our job to know the difference. It is the same with your neighbor or a politician. Why would I believe a politician is a believer if they vote for abortions? If my pastor said in his sermon that God ordains homosexual marriage, then either he leaves, or I leave, there can be no compromise on the Truth of the Bible. It's the same with a political party. We may differ on a border fence or support for NASA, but I don't see any daylight for abortion or homosexuality. If he says he is a Christian, he is a liar, it's that simple.

True. Doesn't mean we shouldn't do something about it though.
