Controversial?
People have different tastes so they like different setups. These days people want every question to be stated in the form of irascible polarity - is this or that true. However, a difference of opinion is only as controversial as the two people involved make it. Many differences are only differences of small order.
In high school, my best friend and I only agreed on one thing: music, and not all of it. He loved
Roxy Music. I couldn't stand them. On every other subject under the sun we seemed to disagree. Was it controversial? No. It was genial. We liked each other and extended to one another ability to hold opposing viewpoints. We attempted to figure out what the other would think of an idea and would laugh at both our successes and failures on that score.
There was a song about a poem back at the beginning of the '70s. I like the first paragraph of the poem.
Go placidly amid the noise and haste,
and remember what peace there may be in silence.
As far as possible without surrender
be on good terms with all persons.
Speak your truth quietly and clearly;
and listen to others,
even the dull and the ignorant;
they too have their story.
Max Ehrmann, Desiderata
