Muslim refugees' flight from misery to European societies they often don't like

They obviously do not like the countries from whence they hail. They dislike Pakistan, Afghanistan, Iraq, Syria, Lebanon, Libya, Egypt, Eritrea, Sudan, Nigeria, Somalia and many others that are Islamic. The true refugees among them do not seek shelter in other Islamic countries close to home that are safe havens.
These Muslim migrants are not happy in Islamic countries. Yes, some of the countries are war-torn, but most are not. The one thing they have in common is impoverishment and the Islamic culture with its brutal Sharia law.
These people, in their millions, risk life and limb, while paying large sums of money to illegal traffickers in a desperate effort to reach the European continent by whatever means. They bring with them their culture, the same culture from which they have fled, and set about imposing their alien culture on their host countries.
Europe is being overrun with polygamy and mosques and Sharia law by people who do not speak European languages. They do not convert to Christianity, discard their veils and integrate into European culture, so they are not happy in Europe either. They demand everything for free from medicine to accommodation while discarding free food that they consider is past its sell-by date. When this source of altruistic welfare dries up, Europe will become impoverished like the abandoned Islamic lands.
If these migrants are not happy in Islamic countries and they are not happy with European culture, how will they ever be happy when Europe becomes Islamised, increasingly resembling the counties from which they escaped?
Having smothered the European culture with their cultural misery and discontent, they will also have denied Europeans their culture and civilisation evolved over millennia – all in the name of Islam.
It seems an exodus from misery to total destruction.
