I didn't know how to help keep him from destroying the conversation. I felt like confronting him and trying to, like, Win An Argument with him would just take up the whole time and derail entirely, so I wanted to de-escalate instead of escalate, but not responding at all put the burden on the rest of the group (mostly women) and felt bad. IDK. It was not great and I wish I had better tools to deal with that kind of situation.
