I like to play Devil's Advocate, but...

I like to play the devil's advocate, I don't like to go along with what mainstream thought tells us to think, I like to think for myself. However, I also sometimes see people that act like that, but seem to be trying hard to be different/edgy just for the sake of being "edgy". It's good, I love challenging ideas, but there is just that point where it seems they are posing, they like the idea of being a creative intellectual challenging ideas, but don't even know anything about subjects they claim to be passionate about. I see being edgy as being well informed on issues and having well founded ideas on them, rather than ticking off a checklist on what you need to look like you think to be "different". At one point do you think someone becomes an edgy poser instead of being thoughtful?
