Increasingly over the last years, whenever there's an article in the paper about something that can be tied to feminism/women's rights/some person who happens to be a woman and actually dares to voice an opinion, men stop by to comment and say 'THAT's why we go out of the country to find wives!'
Because in their opinion, women in Thailand etc. are 'real' women, they have the right priorities (taking care of their families), and they know who's the man in the house. Yeah, and they're always beautiful, sweet, and love you for the man you are - and they never complain, either.
There have been some horrible cases of men finding wives in other countries, treating them like slaves, and then divorcing them just before they would have the right to apply for citizenship (not sure what the right term is), so that they have to go back to the situation they tried to escape, while the men find new wives, and repeat. Women who have been completely isolated, forced to work all day, beaten, and even forced to sleep on the floor. It's terrible. I'm hoping these are extreme examples, and that most of the 'imported' wives find a marriage they can be happy with.
I know that some of them despair because everybody around them suppose that they are 'sex slaves' or married their husband because of his money, especially if they are from Russia or Thailand. So it's difficult for them to find friends because of this prejudice. The men also feel judged once they disclose that their wife is from one of these countries. It seems you can marry out of the country for love if your spouse is from a Western country, but once you find someone from another place, you're automatically an abusive bastard (if male) or a sex-starved adventuress looking for something exotic (if female).
I do think marriages between different countries are on the up, but I think most of that is due to people with Indian/Pakistani background choosing spouses from their country of origin, and people in general finding loved ones through work in other Western countries. This is Norway, though, don't know about UK. When you listen to these men muttering about how all men now choose wives from abroad, it doesn't take that long to realise that by 'all men' they mean, well, themselves.
