This thread is a week old and your contribution is rather too late considering you only remember two British film directors.
Whether you mean to be rude or not is irrelevant, because you are.
First, I can post to a thread if it is a year old if I want to. It's an online forum, not a freaking dinner party. I don't get your point, probably because you are just imposing your preferences on other people, and I'm not interested. I would venture to guess that there are a few people out there with an interest in the topic, even *gasp* a week later. Well, there's myself, for one. If it's truly no longer relevant, then no one will read it anyway.
Second, there are numerous very talented British film directors. I'm not sure what declining to go on with a list of them has to do with countering the claim that there are NO decent British Film directors. One > none, especially considering that the person to introduce this claim simply rattled off one director per country as evidence of contribution.
Ang Lee is Taiwanese, by the way. Equating Chinese with Taiwanese is offensive to a great number of Taiwanese people. You could, by the same sloppy classification, suggest that Miike is a Mongolian filmmaker, which is absurd.
In any case, I think overlooking Hitchcock is a major oversight.
