That sounds like discrimination in the other direction to me. In US you are given a license and you can choose who officiates that license. If you are not religious, you can have a Judge or a government official officiate your wadding. If you are religious, you are free to use a minister of your choice. This way neither side is discriminated against.
From what you are describing, in EU you HAVE to be married by a government official even if you are religious. That's the wrong attitude to take. To each their own, let the people choose.
From bureaucratic perspective the important part is that the state is aware of the "social contract" two people made between each other and there is a witness who witnessed the "execution" of that contract. That's all. Who that witness is, as long as they are trustworthy, shouldn't matter.
You talk about the EU as if it is one legal jurisdiction. We in fact have 28. In Sweden you can get married either by a government official or by a vicar in the church (but only apparently a vicar of the Church of Sweden).
You right, I should have said Netherlands, because I was replying to that specific example by the parent comment, and after doing some research, it looks like EU is all over the place on this topic.
