You can't wake up one day and say 'I'm for gay marriage ' and wake up the next day and say 'I'm against it.' Wake up one day and say 'I'm pro-choice ' and the next day wake up and say 'I'm pro-life.' There's no credibility there.
I actually use a computer a lot. I have three computers that I use on a regular basis - one is on my desk top in my Washington office another is at home and I have my laptop that I use when I'm travelling.
