I am not. The basic meaning of the word majority means greater number. Open out of the three got the greater number. I think you misunderstand what the word means.
With respect, yes you are.
Yes, the word majority does mean greater .. but in the context of votes like this, it is always "the greater number of votes" which has been set at 50%+1 .. this is an internationally recognised and approved and agreed upon value.
.. but sure.. fine .. let's use majority meaning "greater number."
Open players: 6,168
Non-open players: 6,433
Non-open players = majority.
So, yeah.. either way, still not majority.
