They say gender is just a concept.
But even for those who believe that it is meaningless, scrapping it altogether could be a bit much.
But that's just what's been proposed by a committee in Brighton Council which has suggested axing the labels 'Mr and Mrs' from official forms - as it offends transgender people.
The committee's proposal has been met with a mixed response
Green Party deputy leader Phelim MacCafferty said: "Trans people aren't necessarily male or female and sometimes they don't want to be defined by their gender.
"Putting Mr and Mrs on a form is completely useless."
But Dawn Barrett, a Conservative councillor for Hangleton and Knoll, said the idea was "ludicrous".
"How are they going to address letters properly? This is just political correctness gone too far."
Rob Shephard, a spokesperson for Brighton and Hove Green Party told The Huffington Post UK the plans will be considered but nothing was confirmed yet.
"The panel's looking at this idea, they haven't made their mind up yet," he said.
"It's an advisory panel. It's looking at possible ways of improving equalities as far as gender is concerned and then they'll come back with their recommendations. It's not actually council policy, it's just small panel of people who are looking at an idea that has been put forward."
