There are shitcoiners with legitimate confusion, and they might think that they already know about bitcoin or they know enough about bitcoin.. so frequently a person will not know what they don't know, so even smart people can get sucked into various shitcoin talking points without actually realizing that they have little to no clue in regards to what bitcoin is.
That's very true some persons actually think they know about bitcoin and would even engage in conversations about it but don't realise that they don't know what they are supposed to know like the empowerment side of bitcoin and how it is a better asset than other shitcoins.
Another thing is that there likely are a lot of people who have heard of the word bitcoin, and they might think that they have some kind of a decent idea what it is, yet merely hearing the word and sometimes hearing some mainstream rendition of what it is, is not enough to actually realize actually what bitcoin is.. and so actually understanding ideas of sound money might be a bit more foreign to people than we presume such a topic as "common sense" when there are a lot of ways that people can get sucked into believing they know more than they do, and it may well be a good idea for some of them to actually spend a bit of time really studying bitcoin specifically.. whether it takes 10, 50, 100, 500 or 1,000 hours of study may well vary from person to person and the kind of source materials they are studying.
IMO I think from what yoir saying there is a lesson that everyone needs to do some personal research to learn more about bitcoin and have an understanding of how it works and best to approach it, but another thing is how can these new persons understand what is a good knowledge from bad knowledge since they most likely don't know or have any idea on how to differentiate good knowledge from bad knowledge and most influenecers on social media or sources of knowledge they trust can also carry a lot of misleading information that would potentially lead them astray to shitcoins or even gambling practices like buying at low price and selling at high price, there are very few sources of good information with regards to bitcoin online, unless maybe some other communities like this forum, that information goes through confirmation from a lot of persons.
Some folks have a lot of difficulties distinguishing between good information and bad information, and they might actually believe the sources of their bad information and believe that their bad information is good information, and so when they actually come across some accurate and informative information about bitcoin, they might skeptically conclude that the good information could not be true since it conflicts with what they believe to be credible sources.
What I think is people often believe what they think would favour them and not the harsh truth, swaying words that woudl promise them huge profits would definitely sound better than someone teaching then how to build it slowly through proper planning and accumulation, so most times I still blame the reader or seekers of information cause they chose what they feel is best for them without taking time to properly validate those information if they are misleading or not.
