Yes I can understand where you come from but I cannot say which truth...
Example:
JW beleive Jesus was nailed on the stake...
Yup, I know. Jesus said the word " cross " in the Bible, not " stake ".
Chritistianity, Catholic, Baptist etc beleive Jesus was nailed on the cross...
Mohammed, Buddah, or any beliefs see different... They beleive Jesus is Messiah, Mohammed, etc.. etc... East Indian beleive god with 8 arms..., and more form of gods
But, do they die on the cross just like Jesus did ?
What should we say? How could we critizing to tell them that they are wrong or right? That´s because they were being brought up to beleive kind of religions and learn differently.
We don't need to criticize. We can just show them the scriptures ....to show them what's right from wrong since Jesus says He is the TRUTH, the WAY and the LIFE. Truth, Way and the Life to get them a road to Heaven.
It's the Christians' responsibility to show them the Truth. It doesn't matter if, they were bein' brought up to believe in different kinds of religion. If, we already plant the seeds to them and they still refused to accept Jesus Christ, then, there's always someone else who is Christian will go to them. God will not give up on people while there's still a chance.
I personally beleive that Jesus was nailed on the cross... The priests punished him to death because the people worship only him and look him as King of Israel or Jew, not Priests.
