You're all right in that birth control has not been mentioned directly as of late. However, that neither validates nor discredits the church's stand on the issue. The fact that it's being debated here in this fashion would probably bring some humbling words from President Hinkley himself were he to see it.
"Some even use as an alibi the fact that drugs are not mentioned in the Word of Wisdon. What a miserable excuse! Nor does it mention the dangers of jumping from an overpass onto a busy freeway, or diving into an empty swimming pool . . . common sense would dictate against such behavior . . ."
I love that quote from our current prophet; it reminds me that I don't have to wait for the church to tell me what to do in order to do it. The same goes for tit-for-tat doctrinal disputes. The bottom line is, your own conscience is your guide - you shouldn't worry about what other people are doing or what they think. If you firmly believe that birth control is 100% wrong no matter what, and that most of the church membership will pay a great penalty someday because in your perception they don't take this doctrine seriously enough, you might be right Then again, you might be wrong Are you really understanding the doctrine in it's completeness?
I put this in the category of the law of Moses. Perhaps we're at a point where there is a bigger law that needs to be understood and obeyed first. Could it be that we're at a point where gratuitous sex is so rampant that we need to focus on that before we start bridling sexual relationships within the proper sanctions of marriage? I don't know either, but it's a thought!
Maybe right now there are bigger fish to fry. At any rate, as long as you feel at peace with your decision between you, your spouse, and the Lord, this subject can be dropped. Don't waste time worrying about it or becoming a crusader against artificial birth control . . . YOU have bigger fish to fry in getting that family raised properly
