Saying "its not the Jews" simply immediately outs a commentator as being a shill, uninterested in the truth.
A person saying "yes, it is the Jews, but also the influences of X groups are bad" retains some credibility, or hasn't completely shot it through entirely.
The person offering blanket denial that the Jews are not involved in harming and working against Western/White/Christian civilisation and our families and societies has no credibility.
Might as well argue Bush, Obama and Clinton are really the good guys while you are at it.
