you may be right in that intermarriage leads to assimilation fast. but the uproar of the article isn't saying "let's encourage intermarriage", as if this was a good in itself. it's not about that, but about people being rejected who already are there & who identify strongly as jews, are really serious & knowledgable about it but don't see a need to convert any more than others w/a single jewish parent. & what do you know? people w/a mixed marriage background may want to marry within judaism, if only they were accepted themselves. they often aren't, while many others who automatically are don't give a d.. about their heritage whatsoever. the fallacy is this clinging to the one rule of origin (matrilineal & halakhic) as the only thing that matters /one that always matters more than anything else. the rule may've had its rationale once upon a time but it's meaningless in today's setting. as to assimilation in post-emancipation europe, it didn't need intermarriage to come about.
