It is clear that there is still an attitude of racism in many institutions which in the past have been predominantly white with a white power base, and, disappointingly, there is no reason to expect that the Labour Party will be any different behind its public facade. Parties like to claim the moral high ground when It comes to all forms of racism.
There might be good intentions behind but they all fail when they start to blame white people for being white. and black people for being black. Terms as ''white priviledge'' ''colonism'' etc. are all made up by those who take advantage of it to claim a certain victimhood, but fighting racism and addressing these victimhood's are two different things.
Because trying to adress them together just lead to a futher divide what we see now, in the racism debate, in the trans-debate, in the US in the abortion debate. It just leads to people with strong opinions fortyfing their positions and the people with more moderate opinion simply ignoring it, because if you say can be taken the wrong way and therefore cost you tour job, position etc. etc.
While if you really want to solve issues you not an broader approach, an approach of understanding, but also an approach or refusing to use the same ammo as the screaming minority who feel their position is being undermined. And yes that screaming minority is often over privileged, and often white.
But it's still an minority, just as the colonizers where still a minority, blaming everyone is just as silly as blaming every Russian civilian form Putins campaign of wrongdoings. Doesn't make it more wrong or more right, it should change the focus from us-vs them to how are we getting along better in the future.
I suspect that the reasons for racist attitudes transcend traditional left vs right and just boil down to ignorance and fear.
Reading that article I think the writer's first mistake was expecting anything more from a bunch of privileged kids playing at grown-up politics after he had been involved in politics in a multi-cultural area.
Think it's more down to the fact that politics are a once every four year topic for most poeple, and in many countries politics have been quite stalemate, just like the Tories are in the power for years here, the VVD in the Netherlands also for more than 12 years now and more importantly the big parties all known eachother it's all part of the same circle and while it is a bit easyer in the one country then the other to start a new party, really big breaktought's of a new party ''out of the blue'' mostly don't really happen. Think closest in the Netherlands was the Lpf in the early 2000's and in the uk the Ukip, both parties crashed soon after. either by their founders/leader being murdered or walking away and starting an new party.
So people really don't feel that represented anymore.
