I don't watch cable news and I don't pay attention to Jeff Teidrich or whoever so I don't know where this bullshit is coming from. At least one person responding is nominally anti-genocide, so I don't think that's the reason. Another came back with something about the funding bill for FEMA as if it's a gotcha.
What's their logic?
Thought-terminating cliché. If you just proclaim it to be a "right wing talking point" you can dismiss it out of hand without having to engage with the statement. They don't want to have to defend their policy of funding genocide while their own people suffer at it's own merits.
