The dishonesty mentioned is definitely abominable, but life isn't merely two tiers, there are countless tiers. It's easy to mock others, but would you have dated somebody on a wheelchair?
Firstly, I didn't mean to mock anyone, I am genuinely curious as an outsider looking in.
I imagine that there are multiple tiers, just chose A and B for simplicity.
Would I have dated someone in a Wheelchair? - if I am being truly honest, if someone set me up on a date with a girl in a wheelchair, 98% chance I say no (at least to start). But if there was a young woman I had worked with who was in a wheelchair that I had got to know, I'd more than likely have asked her out.
But let me ask you this - how would someone get 'Redt' to someone in a wheelchair? Would they be redt a person with another physical disability? If an able-bodied person is redt to someone in a wheelchair, should they take it as a sign that they're not worthy shidduch material? (like the scene in shababnikim)
On the whole, children of stable homes are healthier than children of broken homes. Of course there are countless exceptions, but you can't fault people for wanting the best.
Define a 'stable' home? Define a broken home? Does someone who lost a parent treated the same as someone who's parents divorced? If one sibling is OTD, is that really always a reflection on the parents or the siblings?
I am firm believer in shades of gray, and look for nuance, and I realize that it's unfair to judge on the small sample sizes of anecdotes I hear from family and friends, but when I hear these stories from people that I care about, I probably feel it's a wider issue, and get saddended over it.
