Why do I say that Islam is an evil religion?

[Untethered]

There are many reasons why Islam is evily.

The word "evil" is meaningless outside of religious language. Since you purport to be an agnostic, you can't use this word without contradicting yourself. 

And there you go, your entire worldview has just been toppled.

 No religion has any authority over words! To actually state that for an Agnostic to make use of the word "evil" is a contradiction of themselves is just about one of the most ridiculous statements I have heard in quite a while.

And there you go; your entire worldview is meaningless in itself.
