Stupidity is when one fails to genuinely see things from some other perspective than their own.

It is not that hard to do, and does not prevent from taking a side eventually, but it helps one to realize that the distance to someone else taking a radially oposite approach is usualy not that large.

Unfortunately, this kind of mind gymnastic is rarely encouraged because it goes against the creation of stronger social circles I guess.

So, all that to say: don't give up. Cynicism is like a drug that feels right at the begining but that will damage a brain eventually.
