Koing: In another time, your mom's advice would have been exactly right, it still may be valid though. If your GF's parents are very traditional, you could run into problems with them trying to fix her up and not accepting anyone she may choose. These situations are rare outside of India(perhaps even in India...I dunno) these days, but they could happen. Otherwise, be respectful of your parents, but try to show/explain to them that their fears are unwarranted in England and in this day-and-age.
You will likely experience some kind of racial "tension" throughout your life, but that would have little to do with who you may marry or go out with. You being a minority have probably experienced already how some people seem uncomfortable and insecure around you or other minorities. That's not really racism per se, often it's fear of being thought of being racist. Here's a little blurb of what I've seen in my small(population of 600+) village, in the middle of nowhere(2 hour drive to nearest city of 100k+) in Canada:
The population here is quite diverse.
There is a very large Russian population here, probably close to 50% of the people have some Russian blood, but this group has been here for 5-6 generations. Though many continued to speak Russian, few of the current generation have little knowledge beyond a few words. This ethnic group is basically indistinguishable from other Canadians, so no ethnic tension exists towards them.
The next largest ethnic group is Japanese(3-5%). I don't know the full history of this group, but I believe they arrived here shortly after WWII. They, however, didn't come from Japan directly here, they arrived here after being released from the unjust internment camps that were located some 200km east of here. For the last 2 generations this group has become indistinguishable from other Canadians(culturally), so no ethnic tension exists towards them.
This is where things change somewhat, ethnic Indians(not native NA, but from India)(3ish%). This group was mostly a transient group(in the '70's), coming and going as job availability dictated. Their reputation was damaged by some incidents involving traditional religious conflicts brought over from India. About 20 years ago, some chose to begin living here. For the most part they stick to themselves, though it's likely related to their(seemingly) limited command of English. They are largely first generation immigrants though, holding onto traditional dress, though their kids are as unruly as any other Canadian kid

, so I'd imagine that within a generation or so they'll fit in fine. There is certainly tension, it isn't severe, but this group isn't treated with the same "comfort"(for lack of a better term) as the other groups.
The rest of us are mostly a mishmash(I being Hungarian, NA Indian, German..though I don't identify too much with any of those, except a little Hungarian), of various ethnic backgrounds. There are a handful of NA Indians, Phillipinos, former American Hippies, and supposedly there is some kind of Spanish dancing commune(don't ask me how that works) out in the mountains somewhere.
Sorry for the racial/ethnic breakdown of my backwater, but I thought it may help show how racial tensions work themselves out over time.
