Is it acceptable for Muslims to donate to Christian charities?

The other day I donated to a Christian "get kids off drugs" charity. The Quran says to do good deeds, and the charity seemed consistent with Muslim values, so when they asked for a donation, I obliged. **Question**: Is it acceptable for Muslims to donate to Christian charities? Maybe I'm overthinking this. I don't view Christians as adversaries, but I wonder if it's inappropriate to donate to Christian charities, who may go on to use the money to teach about Jesus in ways that are inconsistent with the Quran.
