"As an observer, when should I feel comfortable interjecting? "
When someones health, life or well being is on the line. I have seen too many women starting / acting scenes just to make some white knight to intervene. There was research where in public woman was being assaulted/abused by man and everyone intervened. Then they switched it around - NOONE CARED.
Besides, feminism was claiming how strong and able to defend themselves women are. So by interjecting you are being SEXIST.
