"Salvation is found in no one else [but Jesus], for there is no other name under heaven given to men by which we must be saved."
-Acts 4:12

While some Christian sects may ignore the Bible, the Bible itself clearly states that the only way into Heaven is through accepted Jesus Christ as your Lord and Saviour.

Also, your analogy is not apt- wearing a symbol to reject Christianity is different from wearing a symbol enforcing the killing of Jews.

Anyway, we can continue a debate in a different medium if you would prefer.
