In the absence of irrelevant descriptors, many people struggle to remember that fascists can seem quite normal in other respects. Giving a few details helps them to imagine the woman. In turn this can quell fallacies that attach to ideas about “respectable” or “nice”.
That doesn’t matter with regard to this woman as her behaviour is now a matter for the courts, but reminds Times readers that the terror threat doesn’t come solely from disaffected louts hopped up on larger & sun exposure (& who may be quite partial to kicking off violently anyhow).
I’d think that in the absence of much to go on about her, they lifted stuff from her Twitter bio.
