JWd - you are comparing apples and oranges. Many Muslims have integrated successfully into the USA and the UK but that has no bearing on the challenges now being faced by some European countries. If the influence of the quran and hadith and the peer pressure of a conservative Muslim community is secondary to your love of personal freedom and liberal democracy then you will do just fine.
That is not the situation of recent arrivals to Europe.
The impact of Muslim immigration to Sweden is horrendous. Germany is also being forced to wake up to the consequences of Merkel's lunacy. Pretending otherwise cedes the floor to the extreme right. Treating people as racists for having concerns about mass immigration is dishonest and counterproductive.
Muslim majority countries have very different attitudes and values from modern western democracies. You cannot absorb hundreds of thousands of people from a different culture and not expect serious social problems. Mass sexual assaults in Germany and pedophile rings in Rotherham is the tip of the iceberg.
