The high Muslim birth rate in Europe hasn't escaped the United Kingdom either. We should be more aggressively concerned that in the UK, Muslims now make up the majority ethnocultural group in the "South Asian Youth" category, since that means that Muslims dominate democratically, culturally, charitably, commercially, and demographically.
The left-wing in Europe are doing the exact same thing the left-wing in India do, which is court the Muslim vote bank and allow/encourage racism against Non-Muslim Indians. South Asians do not receive liberal support and are forced into a "marriage of convenience" with the racist right-wing.
We need to take a long hard look about the construct that is "South Asian". We need to think about categorizing Muslims as a separate ethnocultural group, and about segregating Pakistanis away from South Asians, and also about the ethnic divisions among South Asians.
