You are spot on. This article only proposes that the "conservative that I know" is OK but all other conservatives are evil. It's the same mentally that leads people to conclude that all doctors are money grubbing quacks except for my doctor who is really a good guy. I doubt she learned much about people's beliefs if this reflects her thinking about Judge Alito vis a vis conservatives in general.
And all politicians are scum, except the guy I keep sending back year after year....
