You aren't talking about extreme views, you are talking about being in the minority. Those are very different things. Belief in slavery - particular based on the binary of skin color - is an extreme view even if everyone subscribed to it.
I agree with you. But now we've lost any ability to define "extreme" views; it's only what seems extreme to each person. My views would seem "extreme" to most people. To me, they are normal and society is extreme.
- I think it is extreme to tell people, under pain of being locked in a cage, that they must pay money (taxes) to a group of people so that they may do things that the person finds morally repugnant.
- I think it is extreme to use wealth to create terrifying weapons of mass destruction.
- I think it is extreme to lock people in a cage because they smoked a plant.
- I think it is extreme to set up dictators who rule their people ruthlessly, merely because that particular dictator happens to support "American interests"
- I think it is extreme to offer puppet governments loans at interest, with strings attached demanding that they enslave their population.
- I think it is extreme to pledge allegiance to a piece of cloth.
- I think it is extreme to support a monetary system, the sole purpose of which is the exploitation of the many to preserve the shameful luxury of the few.
- I think it is extreme to take money from the common man and give it as a bailout to a crooked banker.
- I think it is extreme to bomb anyone for any reason.
There's lots more that I think is extreme. The other side of that is this: My extremely sane views are considered "extreme" by the true extremists. So simply defining yourself as "against extremism" is pretty much meaningless.
