Is something being biased necessarily a bad thing?

I always find it amusing when I see complaints of “bias” for something that makes no pretensions of neutrality, like a right-wing podcast or a left-wing magazine. Media like this is not meant to be unbiased, but that seems to be a significant problem when people who are not their target audience come into contact with them. It is also quite obvious that we tend not to see bias when it is in our favor, yet it is glaring when it is not.

Is being “unbiased” always an important goal for reportage/analysis/non-fiction? Can there be true objectivity or neutrality in say, political analysis? Can such things ever be free of agendas? Do you care if something is “biased”?
