As is life.
You'll always find people that oppose everything that makes you... you. Religion, politics (<-- oh and i think you know about that one), ethics, money, fighting (Boxing vs MMA), Operating systems... etc.
For every several pieces of 'shat' you take, you'll find a couple golden nuggets. Those make the difference, builds character and knowledge.
Who knows, it may even help you build the next startup or 'cool app'.
Take the plunge!
(Not all open source projects are like that, fortunately, but running into one or two can sour your view on the whole process.)
