How about "Anti-abortion activist doctor releases study showing that abortion in unhealthy." Are you telling me you wouldn't place the study under extreme scrutiny? When someone shows their ideological bias, and it happens to be extreme (yes, socialism is extreme), and then they also do science in the same field, it is absolutely appropriate to make their biases known and subject them to extra scrutiny.

EDIT>> Just saw your note that you agree about raising awareness to biases. It sounds like we agree on that.
