Neville, you’ve made very good contributions to this thread providing your perspective as a convert to Judaism. Thank you. You’ve also made very accurate comments on the state of Modern Orthodoxy in America today.
I believe yytz is correct. The Israeli rabbanut, for what they’re worth, accepts American Chareidi non-RCA/GPS conversions.
Regarding the topic at hand, be it known that I’ve made what you describe as “before it was cool” comments right here in this CR years ago, long before her father ran for president. Most didn’t make it past the censors but you might find some from back then. That said, I’m not sure why you think it is cool now; where other than here do you see these points being made?
I agree with you that she almost certainly didn’t utilize a rabbanut approved or GPS beis din. The claims that she had used such a beis din only hit the internet rumor mill after Donald was well on his way to the White House. (Not that if it had been GPS approved, that point would change the underlying circumstances of the situation.)
