I bothered to read the article (I have a feeling that most, including the folks complaining about those dismissing it, didn't bother to do so), and honestly, its pretty obvious why many dismissed it outright. The entire piece is more editorial than anything else; it gives maybe one or two lines of actual information, and the rest is just your typical conservative piece about crime and how the "wokes" are ruining everything.
It's honestly surprising just how much nothing is said in it. It doesn't even bother to actually establish what a "Social Justice DA" is, what policy positions they pursue, or what they even do, its just another empty fluff word.
But anyway, the actual evidence listed in the article (along with the report) ironically contradicts the question given here. The report, written by the Law Enforcement Defense Fund, is so desperate to list every possible DA that might have been funded by a group associated with Soros that it devaluates any real critiques about the guy. Sure, they list the classic example of a bad reformist DA in Chelsea Boudin, but they also decide to include the DA of Denver, Indianapolis, Kansas City (both sides), Burlington, Bend, Salt Lake City, Birmingham, Houston, Winnebago County Wisconsin (who's also a Republican), etc, many of whom are either uncontroversial or barely even reformist.
At a certain point, the list just becomes "DAs representing urban centers in America". Explains why one of the few "criticisms" of Soros from the report is that "40% of homicides nationwide occur under these jurisdictions", a very astute observation. /s
What this means though is that many "Soros DAs" are in places where crime rates are quite low and not an issue. Hell, NYC, the whole originator of this idea, has only 1 "Soros-backed" DA, the DA of Manhattan, who's been criticized for being too conservative, not liberal. Long Island, which swung the most to the Rs over the entire debacle, has 0. Therefore, its actually somewhat difficult to tie these DAs to worsening Dem performance at the ballot box. Besides the case of NY, there's not really much to work with here.
No, most people are dismissing it because they don't like what it says. Not accusing you of being one of those people, it really seem s like you read the article.
