Yes, there will be social challenges, as you have already seen in your family. And it probably will be worse in that culture than for a Caucasian American like myself. But it's not the end of the world. IF you love her enough to faithfully share that burden with her and stand up for her, then yes, marry her. She will need your support. She does NOT need a husband who will resent or blame her for any hardship that may come with her albinism.
If you do NOT carry a gene for the same kind of albinism that she has, your children will all be "carriers" (able to pass on the gene to their children), but they will not be affected by albinism. If you DO carry the gene for the same kind of albinism that she has, each of your children has a 50% chance of being born with the condidtion (and all will be carriers, getting the gene from her). About one in 100 people carries an albinism gene. About one in 17,000-20,000 has the condition.
If you are looking for the "perfect" wife and perfect life, you should probably keep looking. If she is good enough for you "as is," if all the good qualities that make you love her are what's important to you, then who cares what anyone else thinks?
