Not hypothetical situation

So if you are part of an church where you are in disagreement with 88% of the people on what you feel is a minor issue, do you leave and find a different church where you agree with the majority or do you stay and stand up for what you believe?   What if you are told that you can never be part of the leadership because you are not like-minded.  What if you already give hours and hours of your time...but are told you can only serve in certain places.  Do you stay and keep serving with a smile on your face or do you feel devalued and become disinclined to serve?
