Check out this sentence from a recent Associated Press report.
Pearce has been a supporter of so-called “school choice” measures at the Legislature.
Reporters use "so-called" when they don't like the title associated with a particular group. Naturally this is only allowed when liberal reporters are critical of conservative groups.
Can you imagine what would happen if a conservative reporter wrote an article about Planned Parenthood contributing to a campaign and described Planned Parenthood as a group that supported...so-called "pro-choice" measures at the Legislature."
The conservative reporter would be unemployed pretty quickly.
