I didn't publicly shame anyone. I pointed out their clear position of privilege to help them learn to apply empathy.

I think helping one another to build empathy is a good thing, and even if the person I replied to is unable to do so, it's possible that observing them tell a disabled person that they don't think their life is any harder will help other third parties such as yourself build that empathy.

I did not flag their original comment, but it's not for no reason it was flagged to death.

Text is a fairly imprecise form of communication. It's pretty common for multiple people to get triggered by misreading a post the same way if such a misread is possible.

In other cases downvoted posts are often the most interesting precisely because they trigger people with points they don't want to consider. I certainly wouldn't cite it as proof of any position.
