They were not play messiah for minorities; they were explaining how some people (i.e. not all minorities) prefer to be addressed in a way different from other people -- the fact that you consider his tone patronising when I don't is proof of that. And the point of the comment is that we should keep that in mind when conversing. Because I'm doing that, I can now imagine why you might consider it patronising, and can try (not necessarily succeed, unfortunately) to make it more palatable to you.

(Unless of course you consider that patronising as well, in which case, my non-patronising advice would be: deal with it. Either way, I hope they'll still be able to make comments like the above in the future :) )
