More than 1000 feminists, including dozens of Victorian academics, have signed an open letter in support of the Andrews government’s proposed legislation to allow people to change the gender on their birth certificate without undergoing surgery.
The bill passed Victoria’s lower house — where Labor has an overwhelming majority — last week, with passage in the upper house likely when state parliament returns next week after the necessary three of 11 crossbenchers publicly backed it.
However, radical feminist academics and the Victorian Women’s Guild have hit back, saying the notion that they are not real feminists is “offensive and farcical” and warning of unintended consequences from the legislation, such as access to women-only spaces by people who are biologically male.
Heartened by the comments, such as:
What nonsense! It is the legislation which has conflated sex and gender. The birth certificate shows birth sex with no reference to "gender" whatever that word may be construed to mean.
The legislation itself seeks to confuse by implying that birth sex, on one's birth certificate, is the same thing as (supposedly fluid) gender and hence should not be put on that certificate.
No description of identifiable physical characteristics - height, weight, sex, eye colour etc - is the least concerned with how one feels about it/gender.
