Notice how humy tries to mislead people into thinking I expect others to prove a negative. When someone claims global warming is mostly man made and I say prove it, am I asking them to prove a negative?
All 'positives' can be reexpressed as 'negatives' and vice versa thus showing the idiocy of your claim it is unreasonable to prove one but not the other.
( + I have already repeatedly shown you the proof )
