Linda Bellos is a businesswoman, radical feminist and gay-rights activist. She was a member of the collective that produced Spare Rib, a British feminist magazine, and was a member of Lambeth Borough Council in London and was the leader of the council from 1986 to 1988. 
The term 'TERF' is widely used as a term of abuse by third wave feminists for second-wave feminists, often with extreme hostility and even threats of violence. Linda was invited, and then un-invited to speak to the Beards Society in Cambridge University, as part of a bitter dispute between factions within feminism.
