You can agree or disagree with these claims, but they are substantive claims. I provided evidence for those claims, and it should in principle be possible for people who disagree to provide evidence against these claims, such as saying, "the Post-Dispatch has a policy of always doing X, which is why Wagman did what he did," or "Wagman has X, Y, Z responsibilities that prevent him from getting quotes on every story." Those would be the types of reasons people could provide in a responsible, adult debate.
However, I submit that for anyone interested in honest and open debate, it is not cool to respond to substantive criticisms with vague dismissals that don't even attempt to address the substance. If I had just called Wagman a name, then it would make sense to respond with a vague dismissal. But I backed up my claims, so any legitimate response would similarly at least attempt to also make substantive claims and to back them up with evidence. So, with that in mind, consider this tweet yesterday from St. Louis Post-Dispatch Reporter Jeremy Kohler:
No substance. No supporting evidence. Nothing. Just a knee-jerk "circling the wagons" response that pretends that there was nothing worth responding to. So naturally, I invited him to expand on his critique:
So far, Kohler has not responded, and has instead moved on to other conversations.
Personally, I would like to think that a reporter at the Post-Dispatch who has time to make defensive remarks on Twitter would be interested in getting to the truth and as such seriously considering criticisms that relate to how journalism should be conducted. But we shall see.
