Jonathan Freedland has an excellent piece in today's Guardian about the double standards of those on the liberal/left in respect of the tendency of some to associate all Muslims with acts of terror, and all Jews with Israeli government policy in Gaza.
Nobody should be subject to abuse, assault or attacks on their property because they share religious beliefs with others who commit atrocities.
In Britain, there remains a nasty, simmering anti-semitism that seems to surface at regular intervals. It is a prejudice which appears to go beyond the fear/dislike of 'other' cultures that seems to underpin many people's attitudes to members of the Muslim community.
Anti-semitism must not be tolerated. But the absolute rejection of anti-semitism is perfectly compatible with condemning Israeli government policy in Gaza, which I do unreservedly. I also condemn Hamas for firing rockets at civilian populations, although I do think the plight of the Palestinian people is as close as any population could get to having just cause for resort to military action against an oppressor.
