not to me, I grew up writing nynorsk and was forced to write bokmål at school when I moved (which I got to know later they had no right to do...)
but at least that means I can read both without problems, and write , ell, not very good nynorsk anymore, but better than most who have Bokmål as main
it's a bit tricky to explain, those who write bokmål have to learn some nynorsk in 8-10th grade, most who write nynorsk automatically learn bokmål as that is what most newspapers, books etc are in
