Opinions are minions.
Opinions rip on reason’s tip.
Opinions of a feather flock together.
One mind’s thought is another mind’s rot.
Opinions are what other people have.
Your thoughts inadmissible; mine are undismissable.
Opinion is a giddy thing; it sprouts in winter, dies in spring.
We remember our opinions but forget their reasons.
Rationality surfaces in the shallow waters of weak opinion.
