Bah. Your comment is probably one of the less informative ones here, so I downvoted you. Look, there are turns of phrase that shouldn't be used by responsible members of certain communities in public. Saying something like "watch out, woman driver" is pretty offensive universally. We can all benefit from a more inclusive and positive language.

However, the original quote of "Django REST framework is an insane framework" sound innocuous enough to me. The problem I have with it is not that it's discriminatory towards the mentally ill. It's that it makes the author sound like a 13 year old kid. They could improve the sentence by using words like fantastic, great, indispensable, useful, etc. Saying that a "framework" is an "insane framework" is really kind of stupid IMHO. The author could have just excluded that meaningless sentence and the article would have been improved as a result.

Edit: also, searching through the comments on this page, you are the only one bringing up the "insane" word and making (bad) puns around it. Your original comment sounds like a reply to something someone did, except nobody here did anything like what you are accusing them of. Perhaps you might want to take to Twitter or Reddit for pointless venting at nobody in particular. </satire>
