Enough of my rambling. What do you think?
The problem is that there's such a fine line between that and political talk in church. Not that political subjects should be taboo per se, but the assumption is that the members of the congregation may have a wide variety of political views. If we bring politics into our Sunday worship, we're going to wind up turning Sunday services into a political forum, and how can we feel the spirit then? How close will we be as brothers and sisters in Christ if, instead of seeing each other as fellow brothers and sisters we see Republican, Democrat, Libertarian, Loony Lefty, Right wingnut, etc...?
But that's the insidious part, isn't it? To a massive extent, issues of morality and politics overlap like never before, and that line is becoming thinner and thinner every day. Some issues are purely political, but some are fully political AND fully moral, like abortion, LGBT issues... what does a Bishop/priest/pastor say about those? Do we just ignore the people in the congregation who are pro-choice but believe, honestly in their heart, that their view is consistent with their religion? (Hard to imagine for some of us, but they're out there.) Do we want to turn a sermon into a pro-life vs pro-choice debate right there in church? I wouldn't go to church if I had that to look forward to.
As you said, the LDS Church is unique in a lot of ways and one of those ways is that we're encouraged to listen to the Holy Spirit when struggling to understand these issues. And if we're doing that, we don't need to be told what our politics should be by the person at the pulpit.
Unfortunately, that does leave us with a lot of bland content on Sunday, which I agree with you on... but I think maybe it's because we're being reinforced in our knowledge and understanding of the basics of the Gospel, so that we can be stronger and better equipped to use our discernment on the more juicy issues. Most of the Mormons I know are pro-life, and yet not once have I ever heard it preached in Church. It doesn't need to be. When your moral compass is pointing in the right direction, everything else attends to itself. Our church doesn't tell us what to think with these issues. It equips us to work that out for ourselves.
