I don't mean this in a rude way, but if you feel it's a waste of time, then don't waste your time participating. There will be and have been others defending from shitcoinery. This question wasn't about a new person wanting to change BTC or copy it, but instead understand what makes it different.
I think we just have differences of opinions when it comes to education and learning.
If learning is a lifelong endeavor, educating others should be too. Sure everyone can read content posted, but it can be difficult to interpret technical/economic concepts important to BTC at the start. Doesn't help that most people's first intro is via shitcoins casinos like Binance/Coinbase via phone apps where everything is pushed on users. Totally understandable how people end up on the shitcoins train before BTC. Sometimes it's easier to learn via conversations with others and different explanations click with different people.
I just don't think educating someone is a waste of time until they prove it to be.
