It's my feed should I not get a say what I see in it and what I don't?
This is what mean by ideology, the idea that it's more important to make sure I see the right things so hopefully I think the right way takes precedent over how it makes me feel. This sort of thing seems to be all what modern journalism is too, it's all through the lens of editorial now.
I don't want to be on Twitter, I'm on Twitter because Google Reader killed RSS and all the bloggers said "What's the big deal? Just use Twitter" because their follower counts going up made them feel good and now I can't get what I used to get from RSS without the unwanted side serving of (mostly) American politics.
