That's the problem with Pollievre's language.
And even pre bottom surgery trans people are vulnerable.
It feels like a given that trans people deserve to be able to use public washrooms and change rooms without fear, and I haven't seen any actual evidence they cause any issues beyond offending some closed minded people.
There are biological female spaces which it makes sense to exclude trans people from, they do have different experiences than cis women when it comes to growing up, periods, giving birth, etc. But bathrooms don't seem like one them.
