Very reasonable thing to say, and yes of course, we're only talking about European values, not skin color or religion if it's practiced privately.
Funny how if you would say that about any other country or civilization in the world, like Japan belongs to Japanese people, everyone would cheer, but Europe? If you don't wish for its destruction and submission to a radical ideology like Islam, well you must be a racist bigot.
We need to address those problems right now, it's been long overdue. A large minority of our population now actively hates Western values, and the problem with beliefs, it's that people end up acting them out and they manifest at the social level.
That's why in Europe, we need to collectively assert our values, what we believe in and assert that there are limits you can't go beyond anymore. For example, you want to wear the hijab? Fine, you can do it publicly, but you can't work in the public sector, you can't wear it at university, in school, and companies can choose whether they'll allow it or not. But we have a right to no like it and point out what it represents: a symbol of the oppression of women and that at the same time implies that men are animals who cannot control their impulses when they see a woman's hair.
No you can't oppress and harass gay or trans people, no a woman must not submit to her husband, no apostates shouldn't be punished by law or killed, and last but not least, no we don't have blasphemy laws and we won't invite the Arab inquisition into our free countries. We don't believe in Islam, we don't believe Mohammed is a prophet or the founder of any religion we follow, we're allowed to mock Islam just like any other religion, and we'll keep on drawing cartoons of Mohammed if it pleases us.
In the end, it's almost all about being able to say 'no'. "No you can't do that". I've had that discussion with my Muslim best friend (no it's not a paradox), and of course, he says that the next step for Muslims if they're told 'no' (meaning they get angry at a cartoon of Mohammed for example) is to become violent. And I'm like: "OK, fine, do that, then we'll be able to target them and say 'out!'" I believe Islam like all rigid ideologies produce some sort of collective narcissism, and what happens when you pop a narcissist's bubble? When you tell them no? Narcissistic rage ensues, which looks like a temper tantrum, which is what the terrorist attacks that already happened all over Europe and the rest of the world ultimately are.
Now that they've been enabled and in some cases empowered for so long, it's going to become even harder to tell them no. But it's now way too late to hope for a soft landing on this issue. We collectively need to stop being such cowards and tell them 'no'.
