Being a Christian is not about specific beliefs about details that may or may not be correct.
Being a Christian IS about the teachings of Jesus.
Love one another, this includes EVERYONE including your enemies. That is what defines a Christian.
When you love one another, you respect all humanity from the womb to the tomb. You wouldn't lie or bear false witness, you would promote real fruits for all.
I've met plenty of JWs,many were looking for anwers and truth and were sincere in their search, but I have never met a Christian JW
