We need every single person eligible to vote to get their say in. While of course I would love for you all to want to allow gay couples to marry, I respect that you may not understand just how important it is, so I'm not asking you to vote against this amendment. If this amendment passes I want to know that it really truly is what the people of California want. I don't really think that it is, but I only know a small portion of the population.
If you don't really care either way, think about if someone decided that people of different races should no longer be able to get married. Doesn't make sense, right? I see this situation as the same thing.
