The alternative is to have less strong and passionate feelings. Like "Oh I wouldn't really do that but that's cool that he is." Why would one need to have such strong opinions about a random guy in a picture?

I think the point is that the hivemind/bandwagon/mob mentality pushes everything to an extreme, because the people with more neutral opinions aren't very motivated to post them.

In the little town where I did born, you're loved or hated. You can't be ignored in a little town.

I've noticed more and more about this, as I move across the world.

How about strong passionate acceptance or tolerance? A resolute desire to give strangers the same consideration you hope to receive from people who don't know you.
