So what I should take from the posts here in favour of turning the other cheek / Christian response, is that I am stupid, rash, ignorant, perhaps inconsiderate of the "home is the castle' paradigm, inexperienced in real life, unknowing of the extremes of violent possibility and even desperate to define my masculinity with barbaric parameters if I turn around and respond, even verbally? Are you all kidding? Do I generally sound rough, uncultured, pervasively violent and inarticulate? Do I appear to be ignorant, stupid or inexperienced in life? Do I seem like a man who wants to be seen as a thug?
No - in case you are hesitating.

Not all situations require the same responses. I presume, when I write any post, that we are all working within a premise that offering advice is fraught and problematic in that we, none of us, is present art the time of any difficulty, living life and looking through the same template of experience and ability to express as the person who lists a thread, prompting advice. I also presume that you are all doing something similar. There are no absolutes; there is always possibility and space to spread meaning and response.
That said, the responses asking people to walk away because there may be an uncomfortable or potentially dangerous counter-action are illogical in that they discount the violence that permeates GLBTQ life almost everywhere, they make irrelevant and sordid and stupid the sacrifices made by people who martyred themselves for the freedoms we mostly take greedily and for granted. The argument this position makes is that there is no advantage to denying space and expression to those who would defame us for our natural same sex attraction, to those who insult us and diminish us groundlessly and with disregard for the frailty of personal circumstances. Such a position of silence and withdrawal is not elegantly strong, more intelligent, authoritative, instructional/educational, or peace enabling. It not only enables abuse, but reinforces notions of a gay boy inability to take a role of dominance even at our own peril. It responds to abuse with a nod of agreement, saying "You're right - I had that coming. The worst you can expect from me is a little sarcasm or back-biting, and a veneer of superiority." When we make such an argument, we fail to read our response from the position of the person we are reacting to - and make no mistake, you are reacting no matter what you do.
I'm not living Pai Mei's life, and may not be giving advice that is appropriate for him (and surely he can discern that for himself, as you all do), but I can think through everything that I endorse and argue my perspectives logically and with an understanding of the many aspects of humanity and inhumanity that play in this field. It isn't a pissing competition - and for those who like to think they alone live in areas of extreme violence all I can say is you remain ignorant of the rest of the world if that is truly your belief. Passive resistance does not work, and there is no example of it ever having worked. It always ends up being the case that others come to the rescue, doing what the passive refuse to do for themselves. Those who do the rescuing end up paying the price disproportionately. If everyone stood up and refused to tolerate abuse, I suspect it would soon enough end the majority of the anguish so many have and continue to face.
