The Muslims are conquering because the British authorities are allowing them that luxury. Where will England be in 50 years? If there are not race riots now, there either will be in the future or Britain will become a Muslim outpost. The authorities have got to regain their sturdy British backbones and get the newcomers to shape up or ship out.
Multiculturalism was formed in the crucible of guilt over the colonial era, but that’s over. Non-western nations are not vastly superior to western ones. Evil exists in the world. It always has and it always will. Western nations colonized much of the third world and produced much suffering; China is colonizing Tibet and producing much suffering; the Japanese did all kinds of horrible things in China during World War II. The list of conquest goes on and on (and it always will). We in the West do not need to repent to the point that we give our civilizations away.
Alas, if that comes to pass I fear it will be worse, much worse. The Muslim religion is like an iceberg. It looks massive but in reality is comprised of numberless contending shards held together by little more than outside force(s). London wouldn't be a "Muslim outpost". It will be Beirut-on-the-Thames.
