I vape in public, but I have a cig-a-like, so most people recognize it for what it is. I also don't puff out clouds of "smoke" like an engine that just threw a rod...

My "smoke cloud" is typical to an analog.
Some of the video clips I've seen of mods show HUGE plumes of vapor that remind me of those mosquito trucks going down the road spraying for mosquitos. If you're one of those types exhaling huges plumes in public, then either you WANT the visual attention or are looking for the confrontation so you can argue that "it's NOT smoking" and you "have the right" to vape away.
Remember, while you may "have the right" to fart in a crowded elevator, it doesn't make it acceptable...
I vape with consideration for others.
