If you or anyone you see steps over the line, get an apology out there and discuss it and move on. Over time what constitutes a transgression seems to get more minor and trivial in my eyes, but until we're at a star trek utopian standard of living, progressing towards it is worthwhile in my view.
Of course if somebody is taking the piss and claiming oppression when there isn't any, they deserve to be called out on that too. In the poster's comment to which you are replying I do think his SO's grievances are valid.
