How has the growing acceptance and visibility of LGBT people affected how straight Americans view sexuality and gender – including their own?  How has it changed the way all of us think about sexuality and gender?  Eric Jansen’s guest this week is Sonoma State University sociology professor James Joseph Dean, author of Straights:  Heterosexuality in Post-Closeted Culture.  He argues that – among other things – the “presumption of heterosexuality has vanished.”  In other words, even straight people can’t expect that others will assume they’re straight, and that affects how they present themselves in the world. Dean’s book examines the changing nature of masculinity, femininity and sexual expression in America, and the emergence of  what he calls “a new kind of heterosexuality.” (Live interview aired 7pm Thursday, July 30, 2015)
