Hate crime is unacceptable. Decrying the rate of the rise seems pointless, unless you are highlighting it as a factor brought on by Brexit. But then there was an 18% rise between 2013/24 & 2014/15 (pre brexit) < ahref=http://www.report-it.org.uk/hate_crimes_reported_to_police_up_18_in_england>Here

So the rise is not a purely Brexit phenomenon.
