TBT,
No bone, just wondering why the silly comment.
If the person is ready to accept the minhagim, kol hakovod, however it can very well be a reason not to get involved. And the differences betweeen an Ashkenazy and Sefaradi are much greater that differences between diffierent chasidus. And that difference too is considered.
To say “why not” shows a lack of understanding in the different mesoros. It is not a matter of one being right and another being wrong, but they are different. And there are a number of cultural differences as well. These are all valid reasons why someone would not go out with Sefardi, Ashkenazy or Chosid and so on. And all that is obvious to anyone who appreciates mesorah.
I am not saying there cannot be fantastic shidduchim, however, it is not for everyone andi s not something that you shake off with “why not”.
