Anyway I understand your point, but this facts is these, you cant get everyone to be on your side at all the times, those that want to embrace bitcoin/Cryptocurrency in general will definitely do that at their own will, you don't need to talk much.
From 2014, to 2016 and early 2017 I spent must of my energy in promoting cryptocurrency in my locality, most of the people is preached to then, gave me a name, each time they sees me on they street, they will call me brother satoshi, and other crazy names.
Those same persons that where calling me names are now seeking for help on how to join the Crypto race! Some of them are already trading cryptocurrency, some are here!
If they are not ready, there's settingly nothing you will do that will convince them, just give them a break, they will act at their own will, do something that will trigger them.
I bought my First laptop with cryptocurrency, just because I wanted to prove to something persons that bitcoin is not worthless, and that really drove them crazy!
