Now, let's see if I could answer these the way a Witness might.
Please keep in mind that all propoganda is intact. So is all self-delusion of which I have no awareness, whatsoever. And now:
What is a JW? A person who is following the scripture which tells us that we ought to be witnesses to God (Jehovah is God's true name and we are the only people who really know it and use it.)
What made you decide to join? Someone showed me how most religions in the world were just FILLED with falsehoods, pagan traditions and lies. I started to see how Jehovah's Witnesses were the ONLY really TRUE followers of the Bible.
Are you happy being a Jehovah's Witness? Oh, YES. JWs are the 'happiest people on earth', just like it says in the Bible.
Why do you go door-to-door? The Bible says that we should preach in these last days and try to lead people to the truth.
How often do you meet? 5 meetings per week on 3 days, not counting field service
144,000 - That is the number of people who will be going to heaven - not all good people as so many religions teach. Most will live here on earth. But the 144,000 will rule everybody else from heaven.
Why no blood? Because the bible CLEARLY says it's wrong.
Organ transplants? We used to think that but now we have better understanding.
Military? No, we only have allegience to Jehovah's kingdom, so why would we fight for any other nation?
What is the Watchtower? It is the magazine that we study and share with people in our door-to-door work. It is a 'study aide' which helps us to gain a better understanding of scripture. (It's sister magazine is 'Awake!')
No holidays - Because they are just a lot of pagan traditions and take away from the REAL holiday, Christ's death. Because that was the really important thing, not his birth.
1975? some people got to thinking the world was going to end in 1975 but the WTS NEVER said that.
Contradictions? They're only human, but if you think you see a contradiction, it's possible that you just don't really understand it. Show me if you find one and I'll ask the elders about it so they could clear it up. Some people claim they find contradictions but they're mostly apostates and you should be very careful about talking with them. They could just be sent by Satan to tempt your faith in the one true God.
Shunned/Thrown out - Nobody is thrown out. Disfellowshipping is something we are instructed to do by the Bible....(etc. etc. - I just can't go on about this one)
Any version? Wouldn't you want to study the truest version? Wouldn't anyone?
Doubts? Oh no. It is Satan who teases our minds with doubt. We believe in the one true religion, Jehovah's Witnesses!
