should god judge america?

Of course God would be justified in judging the sins of America! The Bible says that PEOPLE must not judge, NOT that God shouldn't! He is the only one that can judge. The sins of this country are mounting up so high that if He doesn't bring judgment soon to correct the country, we will all suffer further. (By the way, factory farms cannot be compared in seriousness of sin to abortion and gay marriage! Are animals more important than people to God? That thought is misguided according to the Bible.) According to Romans 1:18-32, the passage of law for gays to have this "right" IS the result of their sins.

I think America has a lot of making up to do. As an American I see so much rudeness and meanness and arrogance everyday. I see it on the highways when I get tailgated. I see backstabbing at work. We are a very boastful nation. I know we have our followers of Christ, but we are definitely a nation in need of some confession and repentance. That's just my opinion though.

Those aren't the number one things I'D worry about God judging America for, but I am very concerned that his patience might be almost up. I'm more concerned about materialism/greed and what we're doing to his creatures on factory farms.

God is already judging America. See Genesis 12:3

According to the bible, judging others is a sin, so no, God should not judge America.
