well, not quite. Rabbi Eliyahu stated that a number of serial killers turned out to be homosexuals.
I don’t know the rabbi thought it necessary to mention this. Most serial killers are male and the number of homosexual serial killers are likely to be mostly male as well.
The only thing that I would deduct from this fact is that homosexual men (sadly) do not differ from their heterosexual counterparts.
But I somewhat have the feeling that the male and self-identified heterosexual rabbi did not want to stress the similarity between hetero- and homosexuals.
