It's important to note every incident where someone is being poisoned with anything we know to be toxic, sure. They all need to be cleaned up. But all I see when I read articles like this is "it's going on everywhere, all the time, so stop worrying". No one is saying these children need medical treatment, that's a false argument. People are saying they need clean water. Arguing any other way is just misleading. And comparing it to other cases of lead pollution like exhaust or paint is again a stupid argument because we banned lead in gas and paint. Those problems aren't solved, but at least they're not getting worse. Meanwhile the Flint water situation was caused directly by the government, who then covered it up until they had to take action. And then still refuse to fix the problem.
It's like if the government wanted to save money so instead of buying new paint for their buildings, they came into your house and pulled the latex paint off your walls. You still have paint on your walls, but it's the lead paint that the latex was covering. It was a contained problem, but now due to actions outside your control, it is suddenly a a problem again and you're expected to fix it. That's what's bullshit about it.
It's like hearing someone say "black lives matter" and someone else steps in and says "all lives matter". Well yes, that's true. But there's a reason people are specifically calling out Flint, and that's because it's a problem caused by the government that now the people impacted are expected to clean up, without having any means to actually perform the work that needs to be done. A mere statement of fact does not begin to describe the situation. It's a matter of principle, of morals.
They weren't "poisoned" and it's just as bad in other places, sure. Now can we fix the damn problem already? Or do you just want to keep making excuses?
