Without wishing to read the mind of DSS, I do have a theory as to why he shouted the phrase he did and why there was such a huge over-reaction, in my opinion.
Many people, myself included, support a commercial and cultural boycott of the state of Israel, including the realm of sport. This, along with pressure from business leaders, lead to the apartheid system falling apart in the early 1990's. Those old enough to remember the rugby tours and rebel cricket tours (Mike Gatting - "it was just a couple of people dancing") will know where I am coming from.
I know, particularly for Dave J, this won't answer why DSS said what he did, but I understand why he did, at least.
The state has, almost since inception, conducted itself in a shameful way, all in the name of self-defence. Laughable, were it not so serious, given that for every Israeli killed since 1948, four Palestinians have been killed as part of the conflict, often including children.
I realise this is not the place for political discussion, so I'll go back to the repercussions of what DSS said.
Unfortunately, for whatever reason, any criticism of the Israeli state is viewed as anti-semitic by a great number of people, as a result of pressure from the very powerful pro-Israeli lobby. This has most likely lead to the quite ridiculous reaction by the police, albeit indirectly.
I am of the opinion that had he championed the Israeli cause, he would have been there to see wee Gowser net against the horrible wee turd's team.
"Keep Politics Out of Sport" was one of the slogans used by the organisations who supported the apartheid-era regime in South Africa, including Th*****r's government at the time.
