You know, some years ago, I was friends with a young transexual. The friendship ended bitterly and I want nothing to do with them ever again, but I did learn that this person experienced it as incredibly problematic that conversation routinely defaults to an assumption of "people are either male or female." I don't always get it right, but I do make an effort to use language that implicitly allows for other possibilities, such as a phrase like "whatever your gender" instead of a phrase like "regardless of whether you are male or female."
Similarly, you could have made the same sarcastic point in a way that did not essentially collude with the position you were criticizing by saying something like "Poor people should be invisible" instead of "should stay at home." If you wish to be a genuine advocate for homeless people, instead of getting on your high horse with me -- someone who has self identified as homeless -- in order to defend your ego, you could have apologized or commented that "I hadn't thought of it that way" or any number of other things that would be genuinely understanding, compassionate and respectful instead of worrying so much about your ego and self interest.
If there is some means where I can get a free copy of your movie downloaded to my android tablet, I would be happy to try to watch it some time.
Take care.
