I don't personally use Facebook but your right Facebook is probably even worse than Yahoo comments lol. I love having a debate or talking with Bitcoin with people who are skeptical but are interested in learning more or at least open to hearing about it but your right some people have their mind made up and there's no point in even having a discussion because you can't argue with someone who just says it's like Tulips or who doesn't even know enough to construct a legitimate arguments. There definitely are legitimate concerns or criticisms of crypto but few people against it are even well informed enough to make those arguments and just resort to name calling or saying its a ponzi scheme.
I found your example of the internet funny and it made me think of this photo...
Ugh I wish I would have found this picture when I was debating with my friend...lol. It’s too late now to be like here ya go! I’m right! 😂 sigh.
