I'm pretty sure there's a difference as wide as the Willamette between tithing either 10 or 15 percent of your salary to a church whose mission involves morally mandating LGBTOMGWTFBBQ people out of existence and a pair of pants.

And I grew up Mormon. They're less creepy by leaps and bounds than Imago Dei...and I say this as a disabled woman who got run out of the church for being a gay "sweet spirit".  There are scads of Mormons I trust, most of whom are quite critical of the Church's more hateful policies. 

People from Imago Dei who tithe to that kind of hate uncritically? You'll forgive me for being rather suspicious. You welcome me into your church as an equal and I'll welcome you as an equal, but until then...your Google-fu about someone's pants is completely different than a church which hates me so much it wants me to not exist.
