First, the obvious strawman : "atheist privilege". I'm pretty sure nobody among us calls for this ...

I am not sure of that, and that is why I am asking.

Saying "I should have special rights because I am an atheist"?

Where does that exist and who asks for it?

Enjoying implicit advantages for not being religious, and being unaware of those advantages and insensitive to the disadvantages experienced by religious people?

Where in Europe right now are "religious people" a discriminated or disadvantaged minority?

Islamophobia doesn't count, that's not blanket "religious people". And, if anything, what we still have in large parts of Europe is mainstream religion privilege. If you don't belong to the main religion of the country in question you find yourself at a disadvantage. Of course, as mainstream religion privilege is eroded, the privileged claim persecution.

A society committed to the notion that government is always bad will have bad government. And it doesn't have to be that way. — Paul Krugman
