Voting in Gurdwaras is kind of a 50/50 thing.
The positive for voting is:
1) Peoples voices are able to be herd
2) opportunity is given to others to join in and make changes with in a Gurdwaras
3) people have a choice on who should be voted, so it makes it fair.
The negative for voting is:
1) Gurdwaras is meant to be place of worship, not the head of parliament, so it kind of kills the spiritual path of sikhi, and depending on who is voted for, that person will more likely focus on the control of the Gurdwara rather than making sikhi the main priority
2) Just as politics in the past, present and probably the future. having politics in the Gurdwara could probably cause more problems for the sangat ( and trust me, I know what I'm on about)
3) It is less likely that the person who is voted for has a head of a committee, will not allow there ego get the best of them.
4) "2) opportunity is given to others to join in and make changes with in a Gurdwaras" this can also be a negative, because the changes a committee could make, could be a non sikhi, or a negative change, which could effect the sangat.
so those are my views
