There’s no easy way for us to see non-flag-related mod actions (that’s not to say there isn’t a way, just that there isn’t an easy way). so your best bet is to give us some context - even a link to the topic, in this case, would have helped me figure out what you were talking about (as I didn’t take any actions in there).
As to the actions in question, I took a quick look at the deleted exchange -it’s not about the points either of you were trying to make. When the posts start to become about BBS members instead of the points they’re making, then that crosses the line of FAQ item 1. Debate the position, not the person. Even when the position is upsetting to you. We will defend your right to have your say if you can do so while being respectful to others.
And if others aren’t being respectful to you? Flag, don’t reply in kind.
