not only religious, people that have an ideology are even worst!
Well I would argue religion is one kind of ideology, so yes, other ideologies too.

Politiek... Iedereen houdt van politiek.
As a general statement I do not agree. But if someone gave me unsolicited and unwanted advice on my way of life I would certainly insist that my opinion is more important.
If a native Dutch person tells me one thing about grammar, and someone who just started the Duolingo course tells me something else, then I know whose opinion is more important. And that goes for all kinds of experts, of course.
