DaasYochid:
I actually thought that Popa’s sevara was somewhat different than the sevara I was quoting, and then Popa clarified what he meant and I thought it was an a third sevara:
1) (the sevara I quoted) It is inappropriate to mar the simcha of the wedding with a discussion of such unsavory issues.
2) (Popa’s first way) Bringing up the prospect of divorce at the wedding, weakens the marriage.
3) (Popa’s second way) Making it easier for a woman to get divorced weakens the marriage.
I think the way I quoted it is the best in terms of answering Gavra/ubiquitin’s questions.
