No, in my view, you're probably wasting your time, if you really expect to change someone's mind.
I think the biggest difference between Conservatives and Liberals is that Conservatives think with the logical part of their minds.. "what steps have to happen to make whatever the desired outcome is happen, and how do I do them"; a logical thought process. On the other hands, Liberals tend to process things with their emotions; they tend to think if they want something bad enough, it should be made to happen. They usually don't think though the workable mechanics of how it has to happen.
Since they're not processing info logically, they can't see where they're wrong.
This can be seen in many aspects of their behavior; One of the most apparent ones is rather than present a reasoned argument against a conservative, they try to wish the viewpoint away by silencing the opposing view if they can
This also matches up with human behavior in general, the younger a person is, the more idealistic & fuzzy minded they are, as they age, & (hopefully) learn, they tend to start to think more rationally, this is why as a general rule, the young are more often of a liberal bent, while the older folks are more conservative.
Since the vast majority of internet forums, including Sci Fi's are populated by younger folks, they tend to be more liberal.
As far as the management of media outlets, I suspect they are more concerned with their public image than any real concern about solving the problems of society. Liberal solutions to problems, such as taking $ from those who earn it to those who won't appear to be more compassionate in the short term, although over the long haul, the conservative solution is usually better for the society as a whole. But the management is afraid of a negative public image, so they back the quick fix.
