Considering the homosexual infestation of the priesthood, the push against birth control is gagging on a gnat and swallowing a camel.
Quite the contrary. Endorsing sterile sex, justified only because it's pleasurable, between husband and wife is just the first step down the slippery slope toward endorsing any sexual act for any reason, no matter how trivial. You don't get homosexual activity on the "approved" list without first putting contraceptive heterosexual activity on the list.
Robert Runcie (fmr CofE Abp of Canterbury) admitted this a few years ago, BTW. It's not just my opinion.
Just as an aside, you can fit all of the homosexual priests who regularly preached or taught against contraception in between these two brackets --> []
