WRONG wrong and wrong again. 
WE do tolerate dissent IF it isn't troll like. AND is the result of mental reasoning without snarky and venemous, vitriolic comments that serve no useful purpose except to express hatred along with the worship of money, powe4r, Ayn Rand and extremism. 
That is why I no longer vote Republican -- way far too much hatred and extremism AND the extensive use of cognitive dissonance as well as ad hominem attacks. 
Please recall the many fallacies of Logic. 
I had some terrific priests in college and i learned many things about Logic and Epistemology. 
IF there were no other problems of truth and Logic the Popes JPII and BXVI obfuscated and dissembled to cover up their perfidy and iniquity.
