Re: Racist? Sexist?
Calling it Racist and Sexist based on dodgy stories is classic dog-whistle politics. In a sane world it would be seen for what it is: an unhelpful distraction from whatever the real issues are. In the real world, it works depressingly well for some: it seems to be strongly correlated with tribal identity: indeed, creating such identities perhaps more importantly than playing to them.
As for ANPR, not at all the same: after all, the whole purpose of numberplates is as identifiers, and they're discrete. ANPR is much closer to reading a barcode than recognising a face.
 For values of 'dodgy' including misreported and/or misunderstood.
 Real issues which might include uses that stray - accidentally or otherwise - into racism or sexism.
