That kind of hostility is so pervasive on the internet. That person has some sort of weird axe to grind and they took out their hostility on you for an imagined reason. I sincerely doubt that you did anything to provoke them. Hostility doesn't always require provocation, some people are out looking for a fight and they'll pick one the first chance they get.
Sometimes good faith questions look like sarcasm or sealioning, but there's really no way around that. If someone is so wound up that "hey, can you say more about that?" causes them to lash out then that's a problem on their end, not yours.
