Brighton schoolchildren will be able to signal their preferred pronoun with stickers as part of a wider gender issues awareness campaign.
Badges reading “She, her, hers”, “He, him, his”, “They, them, theirs” and “Trans Ally” are available in libraries, museums and council buildings throughout Brighton and Hove.
For the first time since the My Pronouns Are scheme started last year, stickers will also be available in the city’s secondary schools.
A council spokesperson said: “The badges and stickers help raise awareness that you can’t assume someone’s gender identity and the pronouns they use.
“We know from a range of evidence that gender is more complicated than is traditionally recognised.
“We all define our own gender and we should respect other people’s identities and rights.
“The stickers for the city’s secondary schools are for any young person who wants to show their support for the My Pronouns Are campaign - wearing them is of course voluntary.”
Women’s rights activist Posie Parker told talkRADIO she doubted how “voluntary” the scheme would really be.
She said: “Once some children do it and it is branded as woke and progressive, then other children don’t have a choice but to follow suit.
“I do not think it is the job of a council to promote ideology and I think it is an ideology, it is kind of almost a religion. It is very sinister that the state is getting involved at all.”
Ms Parker acknowledged that while the use of preferred pronouns may seem harmless, she believed it acts as a “gateway” for further trans issues.
She added: “What it does is open the door for the rest of the ideology, so for example what’s to stop a man with a ‘she, her, hers’ badge using a woman’s bathroom?
“It is a very dangerous ideology that very many people who do not know the implications of should not be promoting, and schools especially have no place in doing this.”
