The figures you quote are the percentage of victims by ethnicity. So, for example, the number of black people who have been victims of hate crime. I was referring to the total number of victims by race. I suspect the latter number was in my memory because of how these, and similar, figures have been reported in the past. E.g. https://www.theguardian.com/uk/2006/oct/22/ukcrime.race.
Some back of the envelope calculations suggest that my 'roughly half' is correct given the figures you provide. Of 1000 people in the UK, 920 will be white, and 80 non-white. Given the rate of white hate crime victimisation you gave, .92 white people in that 1000 will be a victim of hate crime. If we lump all the non-white people together and use the highest rate of victimisation (Asian:1.1%) that gives us .88 non-white victims.
The comment I replied to claimed that racism against white people does not exist in the western world. That claim does not appear to be true.
