It should be obvious, without going into every detail, that islam is NOT compatible with enlightened modern democracy.
In recent decades, muslims have been all out to kill Sikhs, Hindus, Jews, Christians, others. Historically they drove the Zoroastrians from Persia. The partition of India was largely on account of muslims.
The underlying premise of islam is spreading by the sword if necessary. Period.
If you know a muslim in the west that says otherwise, they are simply being dishonest (Taqqiya) or not really practicing the theocracy in their lives.
It seems everywhere islam lives, there is trouble, violence, conflict. Philippines. India. Israel. A few examples.
Unfortunately experiments seem to be undertaken. And people getting killed on account of that mistake.
