Above: Rabbi Yosef Mizrachi (Mizrahi)
To be clear, English is not Mizrahi's first language and he clearly spells various words as he pronounces them, not as they are actually spelled. But that is not meant to justify what he wrote in any way. On top of that, Karen Schwartzman tells me she is Shabbat observant, so Mizrahi's accusation against her for being "a mechalel shabbat [piece of] garbage' is not just offensive – it's incorrect.
More of what Rabbi Mizrachi/Mizrahi had to say about that fire.
