That's because of a simple reason: when I say that we are not a good sample to infer things about the audience at large,
I'm including myself. "Sample" here is a term from statistics, check
here if you need more info. Think of us in this thread as the "sample" and the complete fandom as the "population" (another term from statistics), and you should understand why just 3 or 4 people can not be a decent sample of anything.
So, when we discuss about facts, I say facts that can be easily checked elsewhere, not needing to take my word for it. For example, in the MCU SHIELD is dismantled in "The Winter Soldier". I say it's because of the backstage conflict between film and TV studios, and provide a link to a site that has the full details about it. You say that it's because they did not like the role of SHIELD... and it may be interesting to know which is
your source for that.
