Indifference

The most incisive comment on politics to-day is indifference. When men
and women begin to feel that elections and legislatures do not matter
very much, that politics is a rather distant and unimportant exercise,
the reformer might as well put to himself a few searching doubts.
Indifference is a criticism that cuts beneath oppositions and wranglings
by calling the political method itself into question. Leaders in public
affairs recognize this. They know that no attack is so disastrous as
silence, that no invective is so blasting as the wise and indulgent smile
of the people who do not care.

I didn't say that.  Walter Lippmann did, in 1914.
