Now since you watched one side of the issue, shouldn't you see what the other side said about it? at least to not be biased on your judgment?
If two people come to you to solve a problem happened between them, will you listen to only one of them and ignore the other? or you should listen to both of them to be able to have a fair statement?
I do sense some sincerity in your question, so I will recommend you to watch the following:
the speaker is a British convert to Islam who became a scholar later. At least watch enough of the video to get more understanding about Islam.
Go to youtube, and type "Reverts to Islam" and see the other side of the truth.
I sincerely hope that you will find the truth one day.
