I wonder if in the future we'll have more attack that will target this part of the community, something like SegWit2x and Bcash have tried - promising people high profits while saying that Bitcoin will fall because it will get abandoned.
I still feel that "attack" isn't the right word. Do you feel that the OP is trying to attack Bitcoin, or is it just that their views might be a little misguided? Same with the different fork proposals you mentioned. Just because some users might have ideas that don't integrate well with your own beliefs, doesn't necessarily mean we have to presume hostility on their part. People are allowed to have bad ideas every once in a while. It's if/when they take things to excessive levels that we should start to think of it as an attack.
It would be fair to describe the actions of certain individuals in their chosen methods to promote certain fork coins as an attack, but that doesn't mean we can attribute the actions of these particular individuals to
all users of those chains. Nor does it mean the fork coin itself is an attack.
I understand the temptation for people to go with the "
if you're not with me, then you're against me" mentality, but sometimes we take it too far. One could argue there's enough toxic behaviour in the community already and that we don't need to contribute to that by treating every opposing idea as some sort of threat.
