@VoteKosher: What do you have against marrying a cousin? If your scared of genetic diseases- I hear where youre coming from. But if you think they shouldn’t get married because nits weird, a person shouldn’t not marry someone because hes scared of people calling him weird.
Wasn’t there a story recently of a bachur marrying his neice?
Also, I personally know step-siblings who are now happily married to each other.
If the would’ve broke up the shidduch because they were scared about what other people would think, they wouldn’t be happily married.
