I'll ignore the rudeness and respond to the substance- they are not making their home livable, it's in a warzone, it'll still be unlivable but with electricity. And that is not at no cost- they are creating an extremely dangerous situation that could be deadly to people and animals. I might be persuadable if they were the only people who could be hurt by what they're doing but it's a danger to the public. It's not about the formula, it's about the fact that they don't know enough to appreciate the danger of what they're doing.

No need to be piquish. Parent's entitled to their opinion.
