Don't make an avera by writing something you don't know. Accusing someone of not being a convert when you don't even know who did his conversion is an avera whether you like him or not. Whether what he says is good and true or not either way, if he converted then he is a Jew.
I talked to him. Word was that he had a Satmar conversion. There isn't any Satmar Rabbi anywhere claiming any affiliation. He won't say whether he's a Rabbi or not, and it's 100% obvious that he's not, but when you ask him if he's a Jew, he gets really offended. No Rabbi backs him up ever. His Rabbi would have stepped in already. We did research, and at least one of his outpoken supposed followers was an undercover baptist on facebook, so it's 99% likely he's a baptist minister, and .00000000001% likely he actually converted, and since he lies about being a Rabbi, that's almost 100% likely a Rabbi.
We did research after he came to JEWS FOR JUDAISM to promote that secular Jews convert to xtianity because he says it's better for them to loose their share in the world to come that way. If he says that there, I would bet there are sermons elsewhere. It's more of a sin to say that he's a Jew than he isn't.
