Opinions are hazardous. Where opinions are, conflict also is. It is best not to engage with an opinion but rather to slightly turn one’s back on it.
Opinions are not facts. Facts are quiet. That two plus two equals four is a fact. Its factuality is not elevated by shouting it or by putting it on a flag and waving it.
Facts are necessary. Opinions are hats on rats.
As a mental object, an opinion is not a problem. Identification with the object is what creates the problem.
