This is what Ravi said (hence my previous quote useage)
"Because in her criticism of Letterman she implicated an entire group of people as sharing the blame when in reality no one at all besides Letterman is responsible for what he said nor has anyone else ever made such a comment about Palin's daughters.
She is using the situation to cry "bad hollywood!" In other words she is using her daughter to make cheap political talking points.
She's a total skank."
Note the bolded phrase...
So show me where "some" is defined as an "entire" group of people (a.k.a. ALL)?
All you need to do is change the parameters. Its quite easy.
Sarah Palin was, by definition, talking about ALL of a group of people. She was also, probably, talking about SOME of a different group of people.
Logic is fun!
