It's pretty popular. Sweden, the UK and Germany remain amongst the most popular.
Germany has the strongest economy of Europe. Sweden is popular because it's famously secular. There's studies that it's a magnet for Middle-Eastern immigrants who are anti-Islamists. Arabs and Persians with secular or atheistic leanings.
Anecdotally the most fanatic atheists I know are all Iranian. And it's not just anecdotes. We know that both Sweden and USA became magnets for secular activists and politicians who were forced to flee after Khomeini took power.
This is one of the reasons why Sweden risking Islamism just comes across as alt right hysteria. It's directly transplanting the problems France has had with it's Muslim population onto the rest of Europe. The French Islamic conflict has roots in the French colonial empire. The French ideals of brotherhood and secularism rang a bit hollow when in the 60'ies the colonized people's were wondering where all the equality and brotherhood was to be found. When they started demanding reforms it turned out that it was all talk and France was above all outrageously racist willing to go to any length to subjugate it's brown populations. As far as barbarism goes there's arguably no regime in history worse than the French in Algeria. Possibly rivaled by Leopold in the Kongo. No, shit the African immigrant populations of France got annoyed. So that's what it's about. It's not religious conflicts, it's just racist conflicts.
But the conflicts France has had with it's Muslim population is completely different than any other country in Europe. They're unique. Not Even the UK, who also had an outrageously racist colonial government has had anywhere near the problems France have. Which is a clue. If France had managed their colonies better the they wouldn't have the problems with their Muslim populations as they do. So the religious conflict is just a proxy.
