I have discovered the problem with “some people.”
And, once I realized it, I couldn’t help but think that it was so obvious all along. So here it is: The problem with “some people” is the very identifier itself -- “some people.”
The moment an observation begins, “well, some people believe …” or “some people do not like …,” the person hearing such an observation ought to be skeptical.
It is similar, in my mind, to how the phrase that begins “I’m not being sexist, but …” is always followed by a sexist comment. Note I said similar, not the same.
