Forget gender-neutral bathrooms. One professor revealed his new goal this weekend: gender-neutral holidays.

On the eve of Father’s Day, Preston Mitchum, an adjunct professor at Georgetown University, took to Twitter to condemn the gendered holiday.

With all the debate about single mothers and fatherhood, this is why I wish we would have a PARENT'S DAY and stop gendering everything. — PrestonMitchum (@PrestonMitchum) June 20, 2015

“What I’m trying not to do, however, is discount Caitlyn’s story because of her privileges… but instead use her story to challenge you, me, us about owning our messed up ways of only standing up for people when they are wealthy, not of color, republican [sic], and who has [sic] access to a plethora of resources,” Mitchum wrote in a series of tweets.

Prior to joining Georgetown’s faculty, Mitchum worked for the left-leaning Center for American Progress as an LGBT policy and racial justice analyst. He has previously contributed to Huffington Post and The Atlantic.
