Why not remove the 'Islamic' and the 'Western' and just state:

"The greatest danger to democracy is religious fundamentalism."

It's the whole 'under God' crew, the ones who insist that
'religious freedom' applies to THEIR freedom to observe their
religion and to impose 'god's will' on others, that are
destructive to democracy.

Whether it's Christians in the US trying to legislate what
women can do with their own bodies or Muslims in Turkey
preventing Christian churches from owning property it all
comes down to the same thing.
