The campaign group Jewish Human Rights Watch (JHRW) has accused the Scotttish Palestine Solidarity Campaign of "targeting" a Jewish businessman for selling Israeli goods.
Ally Coutts was found guilty of racially abusing Nisan Ayalon, who operates stalls selling Israeli cosmetics, earlier this month.
Coutts, 57, is a prominent member of the SPSC.
Mr Ayalon, a Jewish businessman based in Aberdeen, owns Jericho SkinCare, which sells products containing minerals extracted from the Dead Sea.
