Exactly Michelle
I get so frustrated when this is weaponised as
a) the chances of it affecting a trans man minister are slim to none (not being ageist but how many ministers are late 20s or early 30s and having children despite being on synthetic testosterone)
b) it wouldn't affect them anyway as they would still get maternity leave
The aggression from those who have a problem with the word mother is because they don't want anyone to use it, not that they just don't want it applied to them.
As PPs say, if the government rule against it and use 'pregnant person' in the Bill this says a lot about what they think matters, or rather, who matters.
