Not blind at all, religion is one of the ideologies based on faith, I gave my support for BCH right after fork because to me it was the right (& now I see, also smart) decision to make
We all live our lives based on enormous amounts of faith, religion or not.
If you hold an ideal you have faith that you're not wrong! You can be wrong for a very long time(watch the markets lol) but eventually it's going to bite you in the ass.
I'm fairly confident about Bitcoin Cash but I'm constantly researching and asking myself and others where I might be wrong! Your idealism = blind faith
