I think if you e.g. added "Disclaimer: this is super left-wing biased" (or equivalently "Disclaimer: this is super right-wing biased") to the top of a heavily biased article, you are not appreciably combating bias.
If you say "Our goal is to represent the views of the right wing", then you're making it clear that you are being honest about your perspective. This then encourages both you and your readers to be aware of the bias, which does combat hidden influence of bias, making it more likely to be a choice.
