It beggars belief. I thought at first that this must be a first year student (as they can often be a bit radical at the beginning of study) but then read:
Dr Ben Pitcher, a senior lecturer in sociology at the University of Westminster
and I am shocked.
Then to read:
Speaking on the same programme, Lola Young, a crossbench peer and former professor of cultural studies, backed Dr Pitcher’s analysis.
She added: “I remember back in the late 80s-early 90s when rhododendrons were seen as this huge problem, and people were talking about going out rhododendron-bashing.
She compared it to a time when P* bashing was something that was all too prevalent on our streets.
surprised me even more - it just shows that position in society is no guarantee of intelligence. So when local authorities take action against Dutch Elm Disease, are they being racist towards the Dutch, when trying to eradicate Japanese Knotweed, are we secretly saying we hate the Japaense 
“Gardeners understand the fluidity of species over space and time.
It would seem they also understand word meaning: non-native: (of a person, plant, or animal) not indigenous or native to a particular place.
As I have said before, people who come out with comments such as Dr Pitcher and Lola Young have in this instance - it says more about their perception of non-British people than it does about anyone else if they can see racism in such things as this.
Doctors and the media best not mention things like Spanish flu anymore as well or who knows where it will all lead.
