“I have seen gross intolerance shown in support of tolerance. ”

“Don't get so tolerant that you tolerate intolerance.”

“Tolerance of intolerance is cowardice.”

“Tolerance is an attitude of reasoned patience toward evil … a forbearance that restrains us from showing anger or inflicting punishment. Tolerance applies only to persons … never to truth. Tolerance applies to the erring, intolerance to the error … Architects are as intolerant about sand as foundations for skyscrapers as doctors are intolerant about germs in the laboratory. Tolerance does not apply to truth or principles. About these things we must be intolerant, and for this kind of intolerance, so much needed to rouse us from sentimental gush, I make a plea. Intolerance of this kind is the foundation of all stability.”

“I have learned silence from the talkative, toleration from the intolerant, and kindness from the unkind; yet strange, I am ungrateful to these teachers.”

“The days of me being "tolerant" are long gone. The days of me being "intolerant" have just begun.”
