No, it is not right to lie. Those folks who do it I don't approve of. I don't even really believe that you are deliberately lying. (Other than the sex stuff I have argued elsewhere, for you are a front line witness to this decadence everyday in your culture in academia and remain .... silent; that is called aiding the enemy via lies of omission).
So, I think you are committed to your version of the truth, but only b/c your horizon of experience, you believe, is fixed at about 12 miles at sea level.
So, lying itself is indeed wrong. I'm wondering how you learned that, and why you believe that too ...
For this Christian can easily state why lying is wrong; but a logician has never been able to defend the statement 'all lying is wrong'.
For though I think you are really out to lunch on almost everything you have written, I'll say this much: you set a great example of what it means to be a black and white defender of the truth. It would be our loss if you really thought you were wasting your time.
If your Mom was dying of cancer, but telling her she would get better would extend her life and give her strength, would you lie to her?
What reason do you have to believe I remain silent?
If you want a non-theistic reason why lying is (generally) wrong, try Kant's first categorical imperative
Kant said that any maxim is ethical only if it can be made into a universal law. So, if you adopt the maxim "I lie when to do so will further my argument"; if everybody did that, then nobody would trust anybody's argument, and arguments themselves would become useless. This would render the maxim contradictory, since if no argument is useful, lying to further one is useless.
