This post appears to show that they're arguing that nuclear bombs "aren't that bad", as it's missing the important context that they're actually talking about the safety of nuclear power — or, rather, they're arguing that nuclear power isn't as dangerous as people might think — by using the lingering radiation from the nuclear bombings as an example.

I want to be clear that I'm not arguing that their argument is sound, but this post is bordering on disinformation.
