>The problem with Islam is that it's extremely malleable. You can pick and choose your sources, scholars and books and have an Islam of your own. Each one has their side, and accuses the other of taking things out of context, or having an incorrect understanding. Some Muslims make heavy use of the No true Scotsman fallacy.
What religions don't have this issue? Using the most popular religion in the US, Christianity has hundreds, if not thousands, of branches that all say they have the "right" version of things, and everyone else is at least slightly wrong.
I'd say it's an argument against any/all religion, really. They can all be devolved into a message of hate and violence.
with the small print that according to their respective writings, muslim apostates or non-muslims are to be killed, while christian apostates are to be met with love and kindness (bless thy enemies, turn the other cheek, love thy neighbour, etc)
