Again, that is the wrong use of the voting system.

No, it's actually the right use of the voting system. We are intended to vote according to our own preferences. You don't deserve upvotes or protection from the opinion of others simply for being on Steem.

The purpose of the downvoting is to promote quality content not to degrade content that doesn't fit in your ideological realm

It's not up to you to decide what I consider quality content. I downvote what I think is bad enough to be worth downvoting.

that is censorship and fascism.

It is neither.
However, noone is going to beat you over the head if you still decide that you want to secede.
