I wouldn't hold the door open for some random woman..
It's 2012.. not the 1920s
Fortunately, the number of British men stuck in the 1950s is reducing :p
I would hold a door open for anyone, male of female.
If the English like you think I'm a w**ker, and my fellow Poles think I'm gay, just because I am willing to open a door for both genders, then so be it - I call it politeness and good upbringing. But I may go against my usual polite and well-brought up nature by telling you all to f*** off if you insult me for being polite :D
