Cross breeding and induced mutation mimic processes that occur in nature and differ only quantitively, say, in the amount of radioactive bombardment of genetic material. Gene splicing, especially between species, is entirely new and qualitatively different.

All I am saying is that it is different. It, if history is a guide, may be a long time before we know if it is a good or bad thing. I am always leery unintended consequences.

And how would you categorize current theories of evolution of species quantitative or qualitative?

How about genetic selection, quantitative or qualitative?

How is cross breeding between different species quantitative when a single gene is qualitative? I think your distinction is non-existent.
