If you're not aware of the problems in India etc, then I suggest it's you that needs to be a bit wider read. The caste system denegrates those of a lower caste, whilst the mysonogistic attitudes treats women as wothless. Attitudes are starting to change, but it's going to take time. In many Arab countries, foreign woman are seen as fair game as they are considered "easy", and treated with contempt for their way of dress.
The people that I have met on my travels, which has not been limited, have treated all foreigners with the utmost respect, and generosity.
Sure, there will always be criminals, and in my experience, they do not really care about the ethnicity (or even the age) of their victims. It is usually the easier targets that become victims of theses criminals, rather than the criminals specifically targeting other 'races'. Unless they are RWR criminals, who will abuse other races intentionally.
I do not think that is the case in the recent incidents, more a case of easier targets, or less risk of apprehension (or even the victim being believed).
Similarly, the Catholic priests do not target specific individuals, more like the easy targets (or less risk of apprehension or the victim being believed). Similarly, abuse in the home by relatives, etc, etc.
Crime prevention works on the same principle, to deter the criminal.
Perhaps there is a failure of society to discuss the crime of abuse of children, with the possible victims, prior to them becoming victims.
Perhaps we should do more of the "Don't go off with strangers!"
Also, you said:
Rape is endemic in come (sic) of their original countries, and the girls quickly learn not to put themselves in dangerous situations, that's why it's the white girls that get targeted,
I can assure you that most females are aware of "learn(ing) not to put themselves in dangerous situations.
And as for rape being endemic in some countries. Have you been reading the comics again?
You will be telling us next that attacks by tigers is endemic in some countries.
