Do they have the right to fail themselves? Is that what you're asking? Why don't you ask yourself that question and provide the answer?
If the metric of "fail themselves" is disagreement with you, then yes, they have the right to disagree with you, and "fail themselves".
And where does that leave them, in the end? Civilized behavior does not arise magically. It arrives through sharing of knowledge and cooperation. There are better examples in this world. Or at least ideas which can be merged.
