I think the root problem is that there is some point where a person is not a Christian just because they say they are. And that Christians are expected to figure that out (judge??) and to shun those types. The body of Christ is not to tolerate new body parts that have all of the appearance of hatred of Christ and the Bible. This is why the modern church is so questionable. Everything looks nice in our society when no one says anything that others don't like to hear. Sweet talk is praised above truth. I fear this will be basically mandated in the Communist future. The hard words of Martin Luther are now considered anti-semitism in the 20th century, and the dolly lama is held up by the masses as the pinnacle of human kindness.
Re-read the words of Jesus, and you will see that he was harsh. When those guys invited him to dinner, he thrashed them. The dolly lama would never do that. He literally thrashed in the temple. The dolly lama would not hurt a fly (except when your back is turned). Our society puts sweet talk above truth. And the truth is that regardless of people's feelings, a high standard indicates that many on this board are in a state of rebellion. Many push the religion that the Bible refers to as accursed. "We" are not all "Christian", and some stuff can't be tolerated. And so there will be sparks. The Bible is the right tool to use to determine which parts are on the body and which parts simply cannot be, regardless of their protestations, moans, and preaching.
For my part, my conscience tells me that it is wrong to remain silent, and be friendly, while others are trashing the gospel by pushing disobedience. That it is easy to have everyone like you, and hard to have everyone hate you.
It is my opinion that if the site were to ban anyone, they should start with extreme anti-Christian theology. It is because the modern church did NOT do that, that there are homosexual "preachers", etc.
