If XR had simply had someone walk up to the Cenotaph, respectfully lay a wreath at the foot, alongside all the other wreaths, then walk away, this debate would not be occuring. Other organisations (including LGBT ones) managed to do so, thus showing respect.
The fact that the man deliberately walked "through" and placed his wreath "above" others, with the action being filmed, is what took the "gesture" from being one of respect, to being a political statement.
It is that aspect that makes it aborrent to me..... respect I can admire... "using" the Act of Remembrance for political purposes I cannot.
