We all live our lives based on enormous amounts of faith, religion or not.
No, faith in something is not same as having ideals.
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
