You moved the goalposts - Auto's question addressed intent, not efficacy.I stand by my answer. While it's possible some tithing funds were used for things such as satellite time, that is hardly the same as donating money to prevent her from getting married. For one thing, I didn't prevent anything - she did get married. In fact, we celebrated it and used it as a teaching opportunity! For another, the principle way members donated resources was by giving money to Protect Marriage - an organization in existence before the LDS church became involved. I did not contribute. I also skipped church and/or walked out when the discussion turned to Prop 8. I also spoke to LDS friends about my POV. So, you see, I did not donate money that prevented her from getting married.
AFAICT, the LDS Church has used its voice and its resources to fight same-sex marriage as long as the same-sex marriage issue has existed. Its stance on the issue is documented at least as far back as the late '90s. If you're going to voluntarily donate money to an organization knowing that at least a portion of it will go to fighting against same-sex marriage, then I think you're culpable for that to the extent that you enabled it.
I don't know whether you think that there are other benefits of donating to the Church that outweight this harm, but it is harm and it is part of the equation.
Sure, it would be like that... if the LDS Church was in the habit of imprisoning people for not tithing.You guys have a funny way of showing support to those who are trying to help you. It's like asking whether you gave money that killed some child in Iraq.
