I believe what started it off was Failed Biopsy saying
"Jewish Gaians Guild? Will you light up my Menorah in my room? Original. Impeach!"
you said... "Antisemitic much?"
and then FB put up a picture of hitler laughing and wrote Oopsie. "I listen to too much Jewish foreplay."
You said you reported them, they asked what they were doing that was bashing jews.
And then you started arguing about if Failed Biopsy was actually bashing Jews or just messing with you.
You called someone scum, they laughed, you said goodbye scum, they laughed that you called them scum twice.
The issue is that they weren't laughing at you for being Jewish, they were mocking you for being so overly sensitive about someone asking if the guild would light a menorah for them.
The best solution to that situation is to be more witty than the trolls, if you can't think of a witty retort, you ignore the person who said it and continue on with your life.
I mean, how offensive is this?

There are nazis in the picture, but is it actually offensive?
Oh and the caption reads as translated from German "Stop! Hammer-Time!"
