Give me a break!

In response to Kenneth Slattery, C.M. (here), who is no doubt a good man, those of who who believe that contraceptive intercourse is *not* immoral are at least--at least!--as warranted in calling those who believe that contraceptive intercourse is immoral "invincibly ignorant" as Kenneth Slattery is in calling us invincibly ignorant.  My God, why can't we just accept that there is room for reasonable disagreement here?
