I think you have to consider a lot of things. Reverts tend to have a completely different culture to most born-muslims, at least as far as indo-paks go. It's very difficult sometimes for the two cultures to meet and that can cause problems - sometimes with the two parties concerned, and sometimes with the actual families. Heck, even amongst born-muslims, there are cultural barriers...so it's certainly not something to overlook nor something particularly new.
Also, reverts tend to be relatively unknown territory for born-muslims. Typically, our in-laws share the same religion. This isn't always the case as far as reverts go - so whilst we can of course accept the revert and their family into our fold, we don't always have strongest connection we should have with the revert's family. This is down to two things: prior to the marriage we usually don't know much about the revert's family at all (who are they; can any of our family, extend or otherwise, vouch for them; do they 'get along' with us; etc) and neither do we share their religion - so it's quite a daunting experience to take on that in all honesty, many would rather not venture in the first place. Marriages have enough difficulties and trials and tribulations as it is - who intentionally wants more on top of that?!
None of this of course is to say we can't or shouldn't marry reverts. It's just there's extra stuff we have to take on board on top of the usual marriage woes and trials and tribulatioons - and so much of it is completely unknown to us.
There are two sayings I think fit perfectly for this topic, so I'll end the post with them. They'll provide you some food for thought too.
1) Take the road less travelled.
2) better the devil you know than the devil you don't.
