You are denying Karites are jews?
i was more thinking of conservative or reform. If a rabbi can not convert, he is not a rabbi. A reform rabbi would not require the amount of study, or the same study topics as a orthodox rabbi. Then you get the whole who is a jew mishagoss, which may not matter as much in the US, but try and go to israel.
