More than political correctness, these efforts toward a gender-inclusive language are based on the premise that language plays an important role in shaping our perceptions of the world around us.
It may seem like a small gesture, but a multi-stall gender-inclusive facility can significantly reduce the risk of harassment, discrimination and stress for all parties.
I think that the single-stall washrooms with the new signs that indicate they're gender-inclusive would be a really great opportunity for everyone to feel comfortable and included in the environment.
