Interracial Marriage/Relaitionships? Do they work??

Growing up in a multicultural Britain, i was always taught that having interracial/multi-cultural relaitionships were perfectly fine and should be encouraged. In principal of course i would always agree.... However in practice do they work??

When 2 people fall in love they always put their differences aside and focus on the similarities & feelings they have between them but as time goes on does that major cultural/racial difference gnaw away at them and actually cause major problems??

I think maybe some of the problems they face could be from the 2 families- for eastern/middle eastern people family is very central in marriage and the two families may cause friction for the couple. Ie- they could have arguments and the couple would find themselves torn between the two.

Another issue is that human race unfortunetly does not see itself as being equal to other races and so one side may feel superior to the other side and may even show this in the way they behave and interact!

Also the children .. they will be half this and half that and also british as well!! Could they grow up with an identity crisis???

In reality its harder than it sounds and i wonder how people do it!!
