>I didn't get hostility from the comment.

Jumping down my throat due to my otherwise benign comment is being hostile. Perhaps a conversation may take place next time; could even instruct me -- as you had here -- that "only reason to link to previous submissions is when there was discussion." Instead, asks leading questions, and some indirect accusation of gatekeeping. That's pretty far to take things based off a four word comment containing two URLs; you had to assume a lot in order to get that bent out of shape.
