I'm really gnostic because I follow a little of everything, but by birth I am Catholic. Like my fellow Catholics here I disagree with the outdated and biased stuff, but it isn't all bad and I participate from time to time. So far every religion I've studied has parts that make sense and parts that are bs. In the end most of them believe in the same basic principles of being good to people, and that is what matters to me.
And ditto on funding someone's missionary trip, heck no! I too have issues with imposing religion on people, as if to say they don't have it right and need outside help. If a church group wanted to go abroad and do good deeds for poor people I would support that, but it's never just that. It's usually more like "here is some food...and the tenants of our religion which you'll need to save your soul". History shows what a terrible idea that is and how much culture is lost along the way. Actually I think it is pretty arrogant.
