Is there some danger of you or others stopping their pot use based on my words? Do you feel threatend in some way?

Revealed, you are, that you feel so defensive. It means you have some quiet, deeply rooted shame or guilt about your habits and are in denial.

It's like this: If someone told me I needed to stop eating vegetables, I wouldn't even bother to respond, so ridiculous is the idea.

If you told me I needed to stop watching Television, I would immediately argue that TV is good for me and I only watch PBS (which would be a lie) and that there's nothing wrong with Television. Why would I argue? Because deep down, I'm trying to convince myself. TV is shit.
