My position is to not do these things as we cannot know the repercussions and we don't have a great track record.
Your position is to try to simulate a volcano to cool the Earth and "let's just see how it goes".
Ignoring the fact if we do that, then a natural volcano could go off as well and set us over the edge, causing an ice age.
Sure you can hand wave away the repercussions pointing to a movie, but it's still your stupid suggestion.
And what retarded logic that is, just because Armageddon is a movie doesn't mean asteroids aren't a threat.
