I think that important part is "opinions also gave a feeling of security".

I see it all the time in my daily life, people are insecure and mostly want some confirmation that choices they made are good ones.

They buy a car and then they start saying that other car brands are bad or breaking so easily. They cannot face the truth if their car turns out to be a crap. Seems totally like programming language bros, and some people cannot stand that in other language they could make more money. So what? There are probably people using that language that make less then them.

I don't want to live such life, I want to make mistakes and pay for them if needed. Lots of choices are reversible or can be changed, be flexible.
