📝 Original message:Sorry, I won't answer to everything, because it's clear you're not listening.
In the HYPOTHETICAL CASE that there's an evil for, the fork being evil
is a PREMISE of that hypothetical case, a GIVEN.
Your claim that "if it's evil, good people would oppose it" is a NON
SEQUITUR, "good people" aren't necessarily perfect and all knowing.
good people can make mistakes, they can be fooled too.
In the hypothetical case that THERE'S AN EVIL FORK, if "good people"
don't complain, it is because they didn't realize that the given fork
was evil. Because in our hypothetical example THE EVIL FORK IS EVIL BY
DEFINITION, THAT'S THE HYPOTHETICAL CASE I WANT TO DISCUSS, not the
hypothetical case where there's a fork some people think it's evil but
it's not really evil.
Repeat with me: in the hypothetical case that there's an evil fork,
then the fork is evil by definition, that's the hypothetical case
we're discussing.
Once you understand what hypothetical case I'm talking about, maybe
you can understand the rest of my reasoning.
But if you don't understand the PREMISES of my example, it is
impossible that you can understand my reasonings about the
hypothetical example.
I'm sorry about the upper cases, but I really don't know how else I
could be clearer about the PREMISES being PREMISES and not just
possibilities. If you can't imagine a scenario where good people don't
oppose an evil fork, then you can't imagine the scenario I'm talking
about, sorry.
Evil fork deployed with speedy trial vs evil fork deployed with BIP8,
that's what I'm talking about.
Please, stop the "then it's not an evil fork" contradiction of the premises.
At this point, I don't think I can be clearer about the main premise
of my example, sorry.
