I've stopped.
The question about AP is interesting. I don't think the UK or Germany would be as "judgemental" based purely on country of origin or religion. I think there is less of an island mentality in Europe as you see in the USA. However, there may well be checks in place during immigration and obviously UK and Germany have similar intelligence gathering resources to use.
Not sure about Canada and Australia...
But Have seen so many of my friends who got UK visa within one month of their visa application. I don't think they do some kind of lengthy security checks.
