Tammy and Jeff take the position that sex (when safe and consensual) is natural,healthy,and good.They want to stop people from using derogatory terms about those,like themselves,who openly engage in an active and non-monogamous sex life.They can be described as

A) swingers.
B) ethical sluts.
C) players.
D) slut-bashers.

Tammy and Jeff's beliefs align with the principles of ethical non-monogamy and they want to combat the negative labeling and stigma that often comes with it. The term "swinger" specifically implies a focus on partner swapping, which may not accurately reflect Tammy and Jeff's approach to non-monogamy. "Players" typically refers to individuals who are primarily interested in casual sex and may not align with Tammy and Jeff's emphasis on safe and consensual behavior. "Slut-bashers" are individuals who engage in shaming or derogatory language towards those who are sexually active, which is the antithesis of Tammy and Jeff's stance. Therefore, "ethical sluts" is the most fitting term.
