Palestinians are not to blame for the actions of a minority of that movement. Tatchell's group were clearly trying to disrupt the demonstration by implying that Palestinians oppress gays. The actions of Hamas deserve condemnation, but why on earth would you charge into a demonstration in favour of freeing Palestine and make it your first order of business to condemn "Palestine" for oppressing gays.
The reaction of people on the demo was only natural. According to eye-witness reports, the reaction was not violent (as Cohen suggests) but merely one of dismay. They were asked to stand at the rear of the demo. Not evicted from the demo, that is, just asked not to disrupt it.
