Obama and McCain agree to forum at Rick Warren's mega-church

I have no problem with the two candidates meeting for a forum such as this. However, when people question Obama's religious beliefs and whether he is a practicing Muslim, than I find it to be very discriminating. No one seems to question McCain and his so called Christianity. As a matter of fact, McCain said that the reason why he doesn't like to talk about his Christianity is because he doesn't wish to impose his beliefs on someone else. Excuse me, but someone asking you about your Christian faith isn't imposing your beliefs on someone else; you're only professing that you claim Jesus Christ as your Personal Savior. There are no Conservative Christians or Liberal Christians; but there are Christians. If you accept Jesus Christ as your Personal Savior and serve him, than you are a Christian. Jesus Christ said that if you are ashamed of me before men; than I will be ashamed of you before the Father. So I gather John McCain is ashamed of Christ? Then this would make him a counterfeit Christian. Conservative Christians talk about abortion and gay marriage. I am against both of these. However, there are other sins that Christ talked about in the bible such as; adultery, lusting after another man or woman in your heart, slander, not rendering unto Ceasar what is Ceasars, racism, murder, lying, stealing, whoremongering, fornication and drunkeness. Have the Conservative Christians kept all of these commandments and not sinned? Have Conservative Christians held President Bush accountable for his behavior? Why didn't Rev. Warren demand a forum in 2000 and 2004 when President Bush and his opponent were running for President, about their Christian beliefs? He would rather focus his attention on the least desirable individual; which is Obama. Conservative Christians need to stop calling themselves Conservative and call themselves Christians; than they need to begin cleaning out their own backyard instead of Obama's.
