At short term this is true, when you start to know what people dont want to know, it is very hard to accept things at beginning, but at long term not being ignorant will enable you to have choices.
Ignorance can be a bad thing, but it's not necessary a bad thing. Yes, I agree I usually want to know as much as I can before making decisions, but sometimes knowing too much makes it harder for you to make the choices you have to make.
