Should one read the Labour supporting,[for their own ends], red top rags with the tits on page 3 in order to get their news? If they want news of Beyonce and the characters in the soaps yes.
If the only papers that carry any intelligent articles are mainly right leaning politically, then it is up to the intelligent reader to detect any political bias and dismiss it.
Bias is in the mind of the beholder in most cases.
