Dear readynow:
regardless of how abhorrent a reform jew may be, the halacha regarding moser is in full force.
Please also do not misuse the words of the Rishon Le Zion since I don’t recall people advising Aurora to go to the “building” the reforms use, in fact I recall posters clearly recommending not to go. In addition, the Rabbi is obviously referring to people who are definitely jewish for all halachical purposes. Aurora needs to go to a Rabbi and clarify her status, and then all decisions will be easier. Incidentally, even in the event someone were non jewish, the conduct outlined in the beginning of my post would be a very serious problem.
A Rabbi might tell someone not to worry about dishes and cutlery, but what about pots? My humble advice to someone who wants to buy kosher meat, is not to touch anything in the kitchen for a full day (go to the restaurant) before buying kosher meat for the first time, and get a new pot for it. It’s not my place to teach, but if someone advises to cook kosher meat in the pot previously used with butter (assuming we believe it ever happened, because I have never seen a jew who was so unintelligent) that person would be some huge am haaretz and arrogant boor. That person should have answered “I do not know”.
