I think the problem is the propaganda about other religions. Islam is being defiled the most right now.
When terrorists claim to follow Islam and bomb buildings, it gives us a view into their most extremist followers. They really have no connection to Islam.
Comparing Islam to the media purported stereotyped followers is something that happens to all religions. If you wanted to learn Islam, you would not go to those people and ask any more than someone wishing to learn about Christianity would approach the KKK. Yes, the KKK is a Christian organization, and just like Islam, the extreme people who are seen following it are actually vastly misrepresentative.
Learn about Islam before you claim it is nothing like Christianity.
