The problem comes when you try to interpret the word of God with a human mind. You are attempting to impose liberal morality onto the divine. It is OK (and very politically correct) to say that Muslims and Buddhists will get into heaven. But I got bad news for you:
"Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice. And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation." (John 5:28-29). In other words, after you die, you shall be brought back to account for your life. Did you read what the scripture said there? Those who have done evil shall be sent to hell for all eternity.
Now, you might be thinking to yourself "well, you know, I'm not such a bad guy. I'm no worse than anyone else". That would be your biggest mistake, sir. The problem is "there is no one righteous, no not one...for all have fallen short of the glory of God" (Romans 3:10;3:23) This means that you, me and everyone else are tainted in the sight of the lord. On the day of judgment :"...there is nothing covered, that shall not be revealed; and hid, that shall not be known." There's no place to hide, you will stand in front of your creator and all your sins will be revealed.
Do you want to hear these words:
"Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels" (Matthew 25:41)
or do you want to be part of this:
"Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him." (1 Corinthians 2:9)
There ain't multiple paths to heaven. The bottom line is this, sir: you and everyobody else in the world are going to hell, and there's only one way to get out of it. False religions will not save you.
