And you’d think that with the Left’s professed dislike of the early Catholic church’s behavior (the Inquisition and all of that), that they would equally dislike Islam’s present behavior. Unfortunately, the irony appears to be lost on them.
No, they don't dislike the Inquisition because of its behavior, but because it was Christian. Similar behavior by Soviet atheists was lauded in the same quarters that denounce the Latin church for the Inquisition.
The sole perfectly consistent feature of the left is that they are Antichristian. (And, yes, capitalizing it and omitting the usual hyphen was quite deliberate.) Consider: they want to overthrow traditional Christian morality (advocating abortion, normalizing sodomy, showing contempt for property rights, . . .); they, incoherently, simultaneously support "gay rights" and the Islamization of Europe (and America) demanding respect for Sharia law, which imposed in all its inglory would execute homosexuals; their policies arrogate to the state the charitable functions of the church and the denigrate private charity, esp. Christian charity, as inferior to government progras, despite massive historical evidence to the contrary; in the specific case of the Obama administration, they will carve out an conscience exception for Muslim objections to insurance, but none for Christian objections to abortion or contraception.
Incidentally, I don't think the Inquisition was a feature of the early Latin church -- it was a good 470 years after the Latins broke off from us Orthodox (which I'll date to 1014 when the filioque was included in the coronation rite of the German Emperor Henry II and the Popes of Rome were dropped form the Diptychs of Constantinople) that they started the Inquisition, almost mid-way from then until now. The most bitter irony, though is that the Latins got the idea the heresy should be a capital crime from the Muslims of "tolerant" Andalusia (no, not really, but from the Almohads who destroyed the brief local period of Islamic tolerance that forms the basis for the mythology of "tolerant" Islam by going back to taking Islam seriously).
