I remember that important piece of information so many years later in my own counseling work. I will often preface my statements with, “in my opinion”. Hopefully, it’s still worth considering, but it’s rarely an absolute statement of scientifically established fact.
I believe many noisy, often angry "debates" would be softened by the person, at the very least, reminding themselves that they are expressing their strongly felt opinion. Again, it is rarely a presentation of an unequivocal scientifically established fact. In this day and age of opposite beliefs: liberal and conservative, religious and anti-religion, gun control and no gun control, immigration, drug legalization, bathrooms, etc., we should remind ourselves we are merely representing our own opinions. They may be worthy of debate, but not the disgust and extreme anger that we have allowed ourselves to be consumed by. That is, in my opinion.
