#250-1. A little inaccuracy sometimes saves a ton of explanation.
-H. H. Munro
#250-2. Lots of times you have to pretend to join a parade in which you're not really interested in order to get where you're going.
#250-3. Whenever you find you are on the side of the majority, it is time to pause and reflect.
In the first quote I believe the keyword is "sometimes", inaccuracy out of sloppiness or ignorance or fear of having to explain is not advised.
The second is about means and ends, putting up with a harmless cause and accomplishing a higher goal. Aimed at those who have the courage to rebel.
The third reminds us not to join and continue with the parade out of comfort and fear to rebel.
