Got in a disagreement online and the other person kept changing their arguments and contradicting themselves. I wasn't overly rude or insulting but after a couple comments my tone was not kind. Suddenly all these people showed up in the discussion getting all butthurt. Even her husband started to get all agro at me in the comments. Apparently she had a stroke at some point and had difficulty organizing her thoughts since. She was objectively wrong and they were all mad at me for trying to give the OP correct information.
