If you're not just attempting to reinforce your own prejudice
Actually I think we all have our own biases or pre-judgements (sometimes a better word to use than prejudice as it makes the point in a slightly better way).
If you only read things that reinforce your bias it doesn't help you to understand where the other party comes from.
The subject here isn't about ideology as such. This is about evidence based medicine. If you believe in evidence based medicine, you SHOULD read stuff that is both for and against.
Reading it does not commit you to agreeing with it. It gives you a chance to examine the strength of evidence and whether arguments for / against have methodology flaws. You should look for ideological bias in the data. As in with all medical issue. Challenging your preconceptions in medicine is an essential part of the process of expanding our understanding of issues and determining when and where studies are utter bollocks and are not worth the paper they are written on. This is how we should judge medical issues primarily rather than because we like what the subject is about.
It helps you to better argue your position ultimately.
Where you go from there, is another issue: implementation of the science requires it to be feasible and work as intended in practice, the understanding that not all people are the same and they might have other considerations that need to be taken into account and all of this has to comply with ethical practices to ensure trust and power between HCP and patients (and possibly their guardians) is always maintained.
I would not treat arguing about medicine in the same way as I would treat arguing about politics. Its a different kettle of fish.
