If your goal is to win the hearts and minds of the masses, then go with the positive approach with information that inspires.
If your goal is to find other people who think like you, then simply say whatever you want to say, positive or negative, and let the like-minded fellows find you.
As for me, I offer ideas and suggestions and perspectives that I believe will be helpful, because my own goal is to simply give people a chance to think about something they might never have thought about before. To pique their curiosity, and encourage them to think for themselves, rather than winning them over or making them think like me.
As I've said, it's all about what your goal is.
