New York Times editor Jonathan Weisman is clearly aware of Donald Trump supporters' history of aggressive racism and anti-Semitism. So maybe he shouldn't be surprised by the reaction to his tweet calling them out for it. But it's hard not to be a little shocked. On Thursday, Weisman referred to Trump's wavering renunciation of former Ku Klux Klan leader David Duke back in February, Melania Trump's justification of the anti-Semitism unleashed on reporter Julia Ioffe for her GQ profile of the would-be first lady last week and Sheldon Adelson's recent appeal for Republican Jewish leaders to support the presumptive GOP nominee for president - all in less than 140 characters. Melania Trump says @juliaioffe provoked vile antisemitism. Klan all in & Adelson urges Jews to back @realDonaldTrump https://t.co/7wFJwVFOSt — Jonathan Weisman (@jonathanweisman) May 19, 2016 Weisman's tweet caught the eye of “Cyber Trump,” who proceeded to bait the Washington, D.C.-based Jewish journalist into a response. @jonathanweisman @AriFleischer do you wish to remain hidden, to be thought one of the goyim by the masses? — CyberTrump (@Rusted_Ovum) May 19, 2016 Thought so. Cc: Sheldon Adelson @AriFleischer https://t.co/UDy7RR9qPV — Jonathan Weisman (@jonathanweisman) May 19, 2016 Flabbergasted that antisemitism in the Trump voter ranks isn't getting more attention, at least from the @RJC. https://t.co/qt5uI5bUIb — Jonathan Weisman (@jonathanweisman) May 19, 2016 After the exchange made waves in the Twitterverse, the anti-Semitic deluge only got far, far worse. Weisman retweeted the responses. @jonathanweisman @RJC You guys can only scream anti-Semite, holocaust and Hitler so many times before people tune you out. — Trump Putsch (@DreadCrash) May 19, 2016 @jonathanweisman @RJC @Rusted_Ovum pic.twitter.com/Xwj2BiWeJ8 — Spectre ✘ (@SpectreReturns) May 19, 2016 @pantsukampf @RebeccaShabad @jonathanweisman pic.twitter.com/LupMDWFQee — Naughty Raspberry (@HelloRaspberry) May 19, 2016 @jonathanweisman pic.twitter.com/iVqpMu22pO — Timmy Norris (@AgentTimothy) May 19, 2016 @cougarhokie @splcenter @jonathanweisman what's wrong with robust debate? pic.twitter.com/T6euB41tAj — Henry Smith (@FoundersRace) May 19, 2016 Pictured: @jonathanweisman pic.twitter.com/yy59dyN2Rv — Mandrake (@vicmandrake) May 19, 2016
