Tim Keller advocates an open Q&A time immediately following the worship service. I've done this for 10 years, and usually find it useful, if moderated well. Keller is in a place with lots more seekers, which colors the way he says things a little differently than we do it, but I really enjoyed this.
Crossway has a helpful article from Romans 14 on how to disagree well on non-essentials.
Speaking of non-essentials, George Will has a good article tearing down the last-ditch argument for voting for Trump: Supreme Court justice nominations.
