From the Pride London statement:
...we are shocked and appalled by this behaviour, not least because some felt threatened by the protesters. We are treating this extremely seriously and will be reviewing what happened with the Greater London Authority, the Metropolitan Police, Westminster City Council, TfL and continuing to consult with our Community Advisory Board.
So 8 women were THREATENING enough at Pride to warrant the involvement of the Met, GLA, TfL and Uncle Tom Cobbley and all. It's the fanjos with their laser beams, ya know. And their teeth. 
We will also be working with groups who have offered support given this issue must be stamped out...
This issue MUST BE STAMPED OUT. Holy fucking Christ. If I hadn't seen it I would have never believed it!
Again, we are sorry to any of our trans siblings and their allies.
But not sorry to their lesbian sisters.
