Lets abstract it a bit and turn it around: should every person immediately have on opinion on any subject or statement as soon as they learn about it? Even if they know absolutely nothing about it, or worse only know falsehoods?

If you think no, then people indeed do not need to have an opinion on something.

People were not doubting? Wut?

I actually thought this was about rolling up cables: circling on the top and over-under at the bottom
