I have interacted with thousands upon thousands of LDS in my 4+ decades on earth. Attended church, Sunday School, LDS seminary, firesides, etc somewhere between one and two thousand times in those years. In all that time, in all those meetings, I could probably number the Mormons I’ve met, who speculated about Christ being married, on one hand. And we’re talking counting fingers here, not like holding sand and counting grains or something like that.
Going to websites where non-LDS folks talk about LDS beliefs, however, you hear about it often, relatively speaking.
