============================
Reading comprehension problems too, eh? I don't think anyone
said that at all. The comments are that selective breeding isn't
necessarily safer than others. In some of these cases, since
'normal' breeding techniques need no safety testing unlike
biotechniques, products can make it to market that are dangerous.

That the current kneejerk reaction to bio-techniques are
disingenuous.
