I don't know...I wouldn't vote for a sister if I didn't think she was qualified for the job. I love my organization, but if my sister's going to be MY representative and she's running for all the wrong reasons, I don't think I could vote for her. It's a personal decision that no one would know about. But--if I was being forced to vote for someone on the basis of being fined if I didn't, I'd make it known that that would be in poor taste. Doing that goes against my GLO's Purpose, so it wouldn't even be a question of loyalty. It just doesn't work like that.
You fine members for missing chapter events--Recruitment rounds, chapter meetings, Initiation events. You don't friggin' fine your members for not voting. Voting is a personal choice, and if you don't want to, you should have the freedom to do so.
