No, they are sabbateans, not jews and it's important that you make the distinction. There are a lot of very good Jewish people waiting for the Messiah.

Sabatai Sevi was a Jewish Rabbi of the 1600's and was thought to be the messaih by some. He had a following of about million until the sultan of Turkey forced him to "Convert to Islam or die" Unlike a real messaih - or even any person of faith, he converted to save his life (It shows you how unimportant his beliefs really are) That happened in the year 1666 & I think that date is significant. I go on here: https://greatawakening.win/p/12jJZIPVET/the-rest-of--revelations-1220-is/

Nevertheless, Most followers left him but some of his followers converted to Islam & joined! LOL Muhammad ibn ʿAbd al-Wahhab founder of Wahhabism (groups like ISIS & el-Qater) was a grandchild of one of those people & they made a pact with the house of Saud

100 years later or so Frank said he was Sevi's reincarnation, had another movement within the Jews & then "converted" to Christianity while keeping his own services. His followers married into the European Nobility Sabateans are required to only marry into their own OR to someone of a higher class. So yes, by now they the European & GCC nobility. There are of course others (Like the people in your link) who stayed "Jews" It's important to know that they are not really Jews though. They are Sabbateans pretending to be Jews. (or sabbateans pretending to be Christians like nobility of Europe, or Sabbateans pretending to be Muslims like the GCC nobility & Wahhab group leaders) A real jew will not kill someone because they know "Thou Shalt Not Kill" A Sabbatean, won't randomly kill someone but they HAVE TO do some vile sin at least once a month (secretly)

Outwardly follow whatever 'religion' they belong to EXTREMLY so but inwardly they know they are doing that in order to break from that & do a real heinous sin deliberately. They are REQUIRED to do what their religion calls a sin every month & they believe it gives them power
