The focus should not be on ' who ' was on the receiving end in an a mature debate but whether or not it is ' acceptable' behaviour.
Our politicians from ALL parties, prior to and after the murder of Jo Cox, have been viewed perversely by many as some species to both verbally and physically attack, some see them as ' Fair Game ' and with the enablement of usually hiding behind anonymity this has reached crisis levels of vile, threatening, harrasment reported constantly.
Whether it be Corbyn or Forage, Right or Left of politics our politicians are NOT ' fair game'.
If it cannot be understood that just because you disagree with another person's politics you condone the act of throwing objects, harrasment, verbal abuse, scribing vile comments /jokes at those you oppose that in turn makes you equally responsible for what is happening, albeit in a less provocative way.
The contempt for politicians as we all witness daily has sunk to the cess pit of abuse. Perversely some people find it OK and amusing if and when it suits their own agenda .
Whether it be an egg thrown at Corbyn or a milkshake thrown at Forage the point is it is a puerile act but there is a serious side and our politicians, indeed anybody, should be allowed to carry out there campaigning free of harrasment.
