Not really, no. While logically inconsistent the form of rhetoric used appeals to humans which are behaviorally dominated by group association. Pointing out its logical inconsistency appeals to a very small subset of the population who probably already agree with you.

What a cynical, defeatist attitude. The Internet is full of people, and you don't know who reads what. Everyone has to learn somewhere, to start from something.

Your logic essentially is, "No one can learn anything; their opinions are fixed," but that's obviously false, as we have all learned or else we would be unable to read and write and do everything else we do.

In fact, your posting your own comment contradicts your logic, as according to it, there's no point to saying what you said, since it can't change anyone's mind.

It is not defeatist to suggest energies would be better spent elsewhere. Defeatism would be if I said we could never convince people of the need for privacy.
