I guess I was surprised that they commented on political language reinvention at all. I've seen it happen a lot over the last decade and there seems to be an automatic adoption of the redefinition of words to fit political aims. Personally, I associate grooming with sexual predators and adolescents. If you're an adult, we say you were manipulated, deceived, or that you're dumb. That said, it was close enough that I could infer what she was talking about.
