"Thinspiration" is a problematic term, and that's explained pretty well in the blog post. The reactions to him using it are largely coming from people who have struggled with or who are very understanding of the struggles with eating disorders, and much of it was initially pretty polite, assuming that he was ignorant of its negative connotations and harmful impact.

Saying "both sides are wrong" is basically absolving Richman of the problematic stuff he said that started this whole thing, which he did not back down from, and that's wrong.

Eating disorders, like a lot of mental illnesses, are difficult beasts to tame. When it's explained that the word is harmful and problematic and it is directly harmful to someone, having the response be "I don't care", that the person who's being called out for their harmful behavior is so actively disinterested in your health and well-being to the point that they would refuse to stop doing something harmful, it's quite a lot to say that someone should remain calm about it.

And it's completely incorrect to say that there's any equivalence between Richman's statements- insults and unforgivable remarks- and the understandably angry responses, which by and large don't involve telling Richman to kill himself.
