Granted. Says much about some of the protesters then, that they hold others to a higher standard than their own.
Why is it strange or wrong for members of a democracy to hold other democracys to a higher standard than tin pot dictatorships?
It isnt really double standards. It is just focusing energy where they think they will get results. Dont get me wrong. Obviously Israel gets way more attention from these types than is justified. My point is that the reason they target you is that they relate to you more than the other side. Many of their arguments pretty much suggest that the other side is what it is and doesnt know any better.
Also, this specific case is to influence the British governments position and the British government is already anti-ISIS. You will demonstrations such of this with the tamil 'genocide' too. Its just much smaller obviously because they dont have the PR.
