I spend a lot of time online, some of that time is spent by choice in my free time, the rest is by necessity as most of my disposable income comes from the internet. When you spend a lot of time online you get to see unsolicited opinions almost constantly, knowing these are opinions and not facts makes them easy to ignore but I do recognise that the ability to differentiate between opinion and fact is a point of critical thinking that people seem to be increasingly lacking.
When you can't tell the difference between an opinion and a fact it leaves you open to influence, some people make entire careers out of exploiting that point of ignorance, people we aptly refer to as influencers.
