Dr. Juanita Bynum What Are You Doing?

Why did Dr. Bynum post this online? Is this a working altar, as some have suggested? I know that this is her honoring the Jewish Holiday Rosh Hashana....which the Jews are now entering the 10 Days of Repentance before Yom Kippur, I was just thrown by this. I’ve seen plenty of Christians have Passover Seders which is also one of the major holidays but never have I seen the holiest day of the Jewish year appropriated. Is this appropriate for a Christian to do?
