As a Mormon I will tell you that Mormons have been Space Mormons since the 1840s.
Which is why I don't think that "tolerance" can really be a virtue. Because tolerance must be inclusive of views that destroy itself.
The reality is that we all have limits to what we consider acceptable behavior in others.
Case in point:
Meaning, you think differing views can only be tolerated when they are not outwardly expressed. But does a person truly have the right to believe what they will if they do not have the right to express that belief outwardly? For any outward expression of one's views would not be tolerated.
What people seem to want is just the right amount of tolerance that includes everything they support, but excludes anyone who disagrees with them.
To put it succinctly, with all the cries for tolerance from all sides, there seems to be little actual tolerance being expressed.
I was being vague as to not get off topic or generate hostilities. By internalized, I mean not negatively affecting other people's lives or freedoms. Express it verbally, sure. Enjoy your personal freedom's, absolutely. Take actions to the point where it affects the way other's live their lives, and it might be a problem. But, that is true of todays culture, but not the past. In the past, it would have been "sticks or stones" .... But in today's world, it seems expressing verbally a dissenting or unpopular position can actual damage oneself, and tolerance seems only a one way street from whatever side is commanding the argument. True tolerance is bi-directional, 100% of the time. Anything else is hypocrisy.
