Scientists can and have been wrong. There are scientists in the world today who believe in contradicting hypothesis. And one of them or all of them might be wrong in their hypothesis.
But that does not stop scientists from sharing their hypothesis. Scientists take what they believe, test it to their own satisfaction, and then share with others. Sharing with others also allows them to
1. Find weaknesses in others' hypothesis
2. Find weaknesses in their own hypothesis
Either way, we should not stop scientific sharing of information if we are to truly progress. Our scientific advances might bring harm if put in the wrong hands but that should not stop us either.
Similarly if we are to make religious progression we should share and debate, as scientists do, our belief. Our debates might not give us the ultimate answer (as in the case of scientists there are many things left unanswered) but stopping the use of this tool of debating to try and find the truth makes no sense.
That is another reason why, if I believe in the truth, I consider my responsibility to share it with my fellow human beings whom I tend to love. All I ask of everyone, including myself, here is honesty.
