What about judging others? Isn't that a sin? Gluttony? Greed? Pride? Self Righteousness? Idolatry? There are a lot more, but I think the point is.....your statement was only part of the truth. Our focus on other people's sin IS the problem with the Church today (and I am a devoted member of the Church, BTW). The Bible doesn't tell us that "gay sin" is any worse than "pride sin")
