Isn't it ironic that a group of polygamists (Mormons) donated the most money against gay marriage?

I am ex-mormon and lived in UT for years and all the polygamist I knew in the UT area were ex-mormons, we had some polygamist who lived three miles away from me, they wore long black robes, looked like burquas, but they were polygamist and they were not mormons, they were ex-mormons, I was there when a few ex-mormon extremist groups killed themselves as well, but never knew of any mormons/LDS people that had extra wives. Maybe women on the side or they cheated with a man, but never extra wives. mayeb FLDS on the arizona/UT border, but never LDS.
