Seriously, how stupid are these posts stating "the people who x are exactly the same people who now y" with absolutely no indication they're actually the same?

This is not a phenomen restricted to r/cryptocurrency, reddit or even the internet, but it's one i stumble upon again and again on this particular sub and it annoys me very much.

There are tens/hundreds of thousands of people that are posting on here. And of course, upvotes and downvotes give some indication of sentiment. All the same, there are different opinions on here and different sentiments co-existing. People screaming "buy the dip" are not necessarily the same who scream "bear market". What makes people assume this? This is not a newspaper with a editorial policy, this is is a community with different people

Rant over, thanks for reading
