No, but it would be nice if material posted came from a person who had some credibility. Lately all these anti-Trump screeds have only been coming from bloggers at the same few unhinged sites, and if that’s the standard for FR we might as well just have everyone post vanities.
What has happened to pasting in context to what one is responding to? It really helps to make things more conversational, doesn't it?
If you do not like the source, why not simply ignore the thread? Or ask Jim to add whatever bothers you to the "not welcome here" list?
Complaining about sources just clogs up discussion and adds zero of real value.
