I updated my post with a few questions to clarify your stance.
The point of the question is to ask whether you think this has 100% chance of not causing issues.
The next step of course would then be to say, okay if it isn't 100% safe then do you support Mexico's right to say, "hey this could cause us or the world harm, stop it".
I'm aware. But if it did cause issues it would concentrate in Mexico and dissipate globally.
But what I'm asking them is.. do they believe it's in Mexico's right to ask a person to stop experimenting on the atmosphere (global or otherwise) from their country.
It's perfectly in line with my position the whole discussion. Laws are arbitrary. Mexico is a soverign country and have the right to have whatever laws they want.
The discussion about what matters matters, even if the subject itself doesn't matter. It is perhaps the most important category of discussion. If we don't know what matters, how can we put our time to good use?
