Who is the Biggest Enemy of Islam?

We all know that currently Muslim World is suffering great devastation. Muslims are in danger all the time. Muslims in Palestine are in a continuous loss due to Israeli war. Other Muslims in other corners of the world are either not in ease, they are also suffering and facing harsh behavior of non Muslim world. We can find examples of violence on Muslims by looking at various sides, like in non Muslim countries Muslim women are not allowed to put veil, some are not allowed to offer prayers.

Question arises that why this all is happening, and this is because the ignorance of other Muslims. Islam says to help each other and to stand or each other but now all our lost in their own world. 
Thus, the biggest enemy of Islam is the ignorant Muslim, whose ignorance has leads him to intolerance, whose action has destroyed true image of Islam.
