Anyways, most Europeans grew up with a very different mindset. I would agree calling them christian ideals in that way. These idealistic and fairly utopic ideals are on one hand paramount for developing countries...but when goodwill and hope substitute realism and logic, it becomes a problem.
However, the problem started with imported crap....from the US. Around the late 2000s, when the 3rd wave femisim got really popular, the Obama administration reigned and the LGBT stuff kept getting attention it flowed slowly into western European countries as well. Took years to be a thing here, but it festered thanks to social media, desperate traditional media, all the fag politicians (although compared to today they weren't that bad...) and "wealthy", young people in search for global justice...and an identity.
All that paired with GWoT fatigue (US was basically leading itself in criticism of the war in the media) and uncovered warcrimes, the people just started disliking the US more and more. The conservative ones had enough of all the gay stuff, the liberal had enough of american conservatism and retardness. Your political, religious and everyday retardness is just not appealing here. Also your tourists are fucking obnoxious, but preferable to Spanish, because those fags scream even more.
No one thinks about the US after WW2 and the Cold War and their (positive) deeds, influence and impact on Europe. Because, not only is it a long and dense part of history that Millenials just didn't grew up with, but also because your country became the pinnacle of gayness for over a decade. If you wouldn't have gotten Trump, you still would be a fag country anyways.
