I always find this kind of "You're completely wrong about this, you have to seek it out for yourself!" reaction sorta funny. Yes, it's very true.
But let's not forget. One of the first songs mormon kids learn is "Follow the prophet.", you are asked to sustain the leaders every year and reaffirm it every time you go for a temple recommend. We often sing "We thank thee oh god for the prophet." Yeah Brigham Young WAS adamant about finding for yourself. But he himself said if you didn't believe the Adam-God theory you were going to hell. Not to mention how many talks are there in conference about following the prophet, or that testify about holiness of the prophet and how we should listen to our leaders.
And that's just what the SLC leaders say. That doesn't even include the stuff in local wards or testimonies or mormon books or artwork or culture.
Yeah, I get it what you're saying, but there's a very good reason people hold the prophet in really high esteem and it's not entirely surprising when people take the "When the leaders speak the thinking is done." tact despite the church saying they shouldn't. Like I often say, "The catholics are taught that the Pope is infallible. And none of the believe it. The mormons are taught their prophets are fallible. And none of them believe it."
Many like to blame the culture on this, but I can't say that I honestly think the church doesn't drive it themselves. You can't show stuff like this on conference:

And then be surprised when some of the membership engage in hero-worship.
