Some of the best things about rationality are:

– a vegetarian arguing in favor of non-vegetarian for their right to have non-veg food

– a person not having beef or pork himself fighting for the right of self-decision of people to have beef or pork

– a non religious person respecting the right of peaceful way of practicing one’s religion

– a non believer respecting one’s right to have belief in almighty

– belief in defending the expression of the ideas that are differing from one’s own ideas

But the above doesn’t mean that logical and rational criticism should be or would be dispensed with.
