"A student at St Andrews University has been found guilty of a racist breach of the peace after he insulted the flag of Israel.
Donnachie has been expelled from St Andrews
The court heard that Donnachie and Mr Colchester entered the halls at 01:30 on 12 March to see another student who shared the flat.
Lithuanian-born Mr Reitblat said he had the 4ft by 3ft flag on the wall after being given it by his brother, an Israeli Defense Forces (IDF) soldier.
He said Donnachie noticed the flag, and said Israel was a terrorist state and the flag was a terrorist symbol. He then unbuttoned his trousers, put his hands down his pants, pulled off a pubic hair and rubbed it over the flag.
Sentencing Donnachie, a history student and member of the Scottish Palestine Solidarity Campaign, sheriff Charlie Macnair said: "This flag was his personal property. I consider that your behaviour did evince malice towards Mr Reitblat because of his presumed membership of Israel. "I'm satisfied that you said Israel was a terrorist state and the flag was a terrorist symbol and I also hold that you said that Mr Reitblat was a terrorist."
Sentence on Donnachie was deferred for background reports.
Outside the court, a tearful Donnachie said he would appeal. He said: "This is a ridiculous conviction. I'm a member of anti-racism campaigns, and I am devastated that as someone who was fought against racism I have been tarnished in this way."
He tarnished himself. He's sure got a funny way of fighting against racism. Just an unthinking Left-indoctrinated fool, I guess.
