Yes, I deleted the comment that claimed that criticism of NFP, failure to use NFP, and/or being against NFP was a mortal sin, or some such nonsense.
This isn't the MHFM website -- it's not permitted to throw around "mortal sin" like it's candy, or confuse "mortal sin" with "disagreeing with me". They are not the same thing. I think some people essentially think they are God: How else can you explain it? They actually consider that being "against me" is being "against God", hence mortal sin.
