As Adam Server writes in The Atlantic, Trump's caravan hysteria (promoted, even with the Soros conspiracy theory connection, on Fox News) clearly motivated the Pittsburgh Synagogue killer.
Of course, those on the Right in media commentary have rushed to the fact that he was not a Trump supporter, thinking that he had also sold out to the Jewish globalists. It's a pretty lame excuse to say "hey, you can't blame us: he started with a completely made up conspiracy supported by Trump and his virtual State television network - but then he went too far!"
As Slate writes in one article:
He was a staunch anti-Semite. A few hours before he set out to kill as many Jews as he could, he echoed a vile conspiracy theory that blames George Soros for most of America’s evils—the same conspiracy that the president himself validated as recently as Friday. And yet, unlike the man suspected of manufacturing the mail bombs, one of which was sent to Soros, the Pittsburgh suspect does not appear to have been a fan of the president’s.In another Slate take: Why Did Synagogue Suspect Believe Migrant Caravan Is Jewish Conspiracy? Maybe He Watched Fox News.
Rather, he regarded Trump as a “globalist” who had sold out to the Jewish world conspiracy.
I note also that there is not a lot of "owning" of this going on in Right wing commentators: Bolt, Blair, Hot Air - all saying nothing about how a Fox News promoted meme fitted right in with right wing terrorism.
I mean, two of those are unlikely to attack Uncle Rupert, but I was hoping someone at Hot Air might have the courage to address it. Probably Allahpundit - as he is hated by many of its readers for being too critical of Trump.
I see that at least Jonah Goldberg has written about how dismaying he finds Right wing belief in conspiracy theories. But this was written before the Saturday killings. He should update it.
Update: Also interesting to note the slackness of Twitter in dealing with false memes, debunked years ago, of a kind that are dangerous in the hands of nutters, so to speak:
