Two things, and that's it from me.
1. In my opinion the idea that anybody, should be able to vape anywhere, is ridiculous. Absolutely, ridiculous. It's not about whether the vapor itself is deemed harmful, not harmful, has nic or not, etc. It's about the fact that you are in CLASS. It's a distraction to those around you, who are also there to LEARN.
So lets take the "vapor" out of the equation, and substitute bubbles instead. Bubbles are harmless. Bubbles are fun. As far as I know, bubbles are also 0 nic. Is it OK for me to blow bubbles in the classroom, board meeting, or movie theater? Of course it isn't! Why? Because it's a distraction! Because it's not conductive to learning. Because it's well, ridiculous.
2. If you are playing devils advocate all the time, it just makes it seem like you are intentionally contrary, and either don't actually have an opinion, or are just looking for a fight.
PS I like waffles.
Edited to add: Now I'm going to do penance in New Members to make up for the time I've spent participating in the two "kids" threads.
