I think people might be getting confused with race and religion here

It's very rare for an Indian family living in England to adopt such harsh line beliefs when it comes to marriage. Most Indians are Hindu's, who, whilst having strong family ties, are normally much more relaxed about the whole thing than Muslims.
The majority of honour killings / family disowning we hear about in the UK is by Muslims, not Hindu's (not saying it doesn't ever go on, but generally).
India is a much more advanced country than some people think. Arranged marriages are totally normal over there, it's the done thing to get your parent's approval before you marry someone. Sometimes the parents even choose the spouse before the couple meet, other times the couple will meet, say, at Uni, and the parents will have to accept him/her before the marriage can take place.
These girls/guys who do this with their parents are normally quite happy to have their input, it's certainly not dusgusting to them, its a normal way of life. Generally in india, Children respect their parents point of views, and having their blessing for their partner is very important.
It's normally in the tiny villages where you hear about these mad stories where parents have forced their 10 yr old daughter into marriage, or disowned their kids if they have married against their will, but that's a very very tiny percentage of India.
India is becoming more modern each day, and a lot of people in their 20's and 30's are highly educated young professionals. Times have changed a lot over there, and arranged marriage - basically having your parents help in finding a life partner - is a normal thing for families to do, it's not disgusting at all.
A good friend of mine recently married his long term girlfriend. Their parents were all friends and introduced them together. It worked out for them and they couldn't be happier.
How often have your parents given you advice on who to date? it's no different. Maybe we should take our parents advice a bit more in our lives!
