There is being respectful and tolerant, and then there is compromising culture and even principles and laws of one's society. Britain and a number of other nations have begun down a road of compromising bedrock principles of free society at the behest of their briskly expanding muslim populations (a great many of which are sympathetic and even loyal not to the culture they have immigrated into, but of the centuries old, religious tyranny, throwback cultures they hail from) and the ignorant, liberal, multi-culturalists that espouse and enable it all in the name of tolerance and respect and often for nothing more than a shortsighted play for an expanded political demographic to vote for them.
Multi-culturalism has run amok in Europe. It is leading to increasing cultural pressures to capitulate, yes capitulate, to the anti-democratic, anti-freedom, anti-political-secularism whims of the fundamentalist and militant Islamicists that have woven themselves into European populations.
This isn't to say multi-culturalism is at its core a flawed concept, I think it has it's place in an open society, but it is being taken to absurd levels in Europe. Much of this capitulation is done under tacit or actual threat of violence, but that just brings us around to the biblical quote in the religion thread: "If you do not stand firm in your faith, you will not stand at all."
We are witnessing, first hand, the crumbling "faith" of Europe in its own principles and culture and how it is leading to the slow fall of a number of nations of the continent. We must see and take this lesson to heart, lest a similar fate befall us.
