I really cannot stand that phrase because it’s commonly used as poor rationale for not favoring a superior approach. Both sides of the debate are pushing for what they consider optimum, not “perfection”.
In the case at hand, I’m on the pro-nuclear side of this. But I would hope I could make a better argument than to claim my opponent is advocating an “impossible perfection”.
emphasis mine:
First of all anti- #GMO stances are often derived from anti-Bayer-Monsanto stances. There is no transparency about whether Monsanto is in the supply chain of any given thing you buy, so boycotting GMO is as accurate as ethical consumers can get to boycotting Monsanto. It would either require pure ignorance or distaste for humanity to support that company with its pernicious history and intent to eventually take control over the world’s food supply.
Then there’s the anti-GMO-tech camp (which is what you had in mind). You have people who are anti-all-GMO and those who are anti-risky-GMO. It’s pure technological ignorance to regard all GMO equally safe or equally unsafe. GMO is an umbrella of many techniques. Some of those techniques are as low risk as cross-breeding in ways that can happens in nature. Other invasive techniques are extremely risky & experimental. You’re wiser if you separate the different GMO techniques and accept the low risk ones while condemning the foolishly risky approaches at the hands of a profit-driven corporation taking every shortcut they can get away with.
So in short:
