Judaism is very different from Christianity but, under the sobriquet of "judeo-Chrsitianity" we too get blamed for the religious inolerance of American society.
Christian reformers, liberals, see that America is flawed by intolerance. coming from Christianity, these reformers assert that the problem is not intrinsic to Christianity buy afflicts all religions. Combine the idea of "Judeo-Christianity" with the bizarre idea that Christians have of forgiving themselves then Jews somehow share the blame for the evils of slavery, evangelism, etc.
As a non Christian growing up in this society, my Paul on the road to Tarsus moments came when I realized that my own tradition really was not responsible for the evil side (or for that matter the good side) of Christendom.
That epiphany is a major reason that I reject meaning laden efforts to lump Abrahamic religions or create a Judeo-Christian common faith.
