Take it up with men and current gender stereotypes.
“The research, conducted with three other colleagues, consisted of seven experiments involving more than 2,000 American and Chinese participants. We showed that there is a psychological link between eco-friendliness and perceptions of femininity. Due to this “green-feminine stereotype,” both men and women judged eco-friendly products, behaviors, and consumers as more feminine than their non-green counterparts. In one experiment, participants of both sexes described an individual who brought a reusable canvas bag to the grocery store as more feminine than someone who used a plastic bag—regardless of whether the shopper was a male or female. In another experiment, participants perceived themselves to be more feminine after recalling a time when they did something good versus bad for the environment.”
