New York Magazine's pop music critic Jody Rosen recently unearthed a "priceless period piece" while helping a friend move.
The 1988 UW-Madison Women's Studies handout "When You Meet A lesbian: Hints for the Heterosexual Woman" lists the following tips:
6. Do not expect her to be as excited about meeting a heterosexual as you may be about meeting a lesbian. She was probably raised with them.
7. Do not immediately start talking about your boyfriend or husband in order to make it clear that you are straight. She probably already knows.
8. Do not tell her it is sexist to prefer women. Do not tell her men are as oppressed by sexism as women and women should help men fight their oppression.
9. Do not assume she hates men. On the other hand, recognize that she may not want to attend an event where there will be men.
13. Do not assume that her lesbian relationship, unlike male-female relationships, are free of problems like envy, communication, failure, struggles with committment, etc.
The hand-out then ends with an activity: "Pretend to be a lesbian for 24 hours. What kinds of things do you notice about how different this feels?"
UPDATE: The list was used in a 1988 classroom, but was published in a 1976 Texas Feminist and Lesbian Newsletter.
This version had quite a few more additions to the list, such as: "If you are tempted to tell her she's taking the easy way out, THINK ABOUT THAT."
