Priestesses?

As I have mentioned before, on occasions I accompany my wife to the local Episcopal church. The Episcopal church ordains both men and women to be priests.
I have attended several times when the services have been led by female priests. It didn't seem very weird to me, perhaps because the services are so different from the Mormon ones.
This leads me to my question: what should we think about female priests in other denominations? Should we support it since they don't have the real (in our opinion of course) priesthood and it doesn't make sense to discriminate? Or should we oppose it so that it doesn't add societal pressure on the Mormon church to open up the priesthood to women?
Obviously, it is none of our business but I still think it is a valid question.
