Attacking the source rather than the content is usually the mark of a poor debating position. If the content is good, the source doesn't matter. If the content is bad, the source's badness will be self-evident.
A debate is a formal event with rules. These are Internet comments. I'm not debating a position. I'm expressing myself. If you think my observation is nonconstructive, that's fine, but it's not because if I were debating I would have made a blunder, it's because we have different expectations and desires in this conversation.
That's fine, I'm just pointing out that your expression is incompatible with basic logic. Saying "this source sucks because x" does not address in any way what they actually said.
Fortunately in this year 2015 we have a thing called hyperlinks via which evidence for assertions can be easily provided. If you treat op-eds from 'unreliable' sources as unreliable, fine. If you refuse to even check well-cited articles from 'unreliable' sources, you're probably more interested in ideological correctness than truth.
There is a nonzero cost of verifying, analyzing, and engaging with any text. The more substantial the text, the larger the cost. I don't have to read another Reason article to know that it's got the same systematic blindspots Reason articles have, and I don't think I could convince anyone of that, so I just communicated my stance and went on. There's nothing 'illogical' about it. I did not state my argument; I just stated my position. I think the charge that this violates basic logic is making a poor assumption: that absence of my argument is the same thing as not having an argument.
I don't want to make the argument. I want to snark about Reason. So I did. Shrug.
