Betty Gallacher is chairman of Bourne Out LGBT, which is organising Eastbourne Pride tomorrow.
Last week she decided to place 20 posters around the town promoting the event.
But she says 12 hours later, a member of staff from East Sussex County Council demanded they be taken down.
Ms Gallacher refused and the council removed them.
She now says: “I can smell homophobia all over this one.
“Why? Because posters put in the same place promoting a fun fair had been there for three weeks.
“Why did the council allow those posters to stay up but demanded mine come down immediately.
“When the council worker called she was rude and aggressive. I am appalled.”Hmmm, really? A gay event, in Brighton, and the council didn't bend over immediately?
*strokes chin* The game is afoot!
A spokesman for East Sussex County Council Highways defended the action. He said: “Where signs can be placed depends on a number of factors but we do not allow them to be attached to safety railings under any circumstances as this could affect visibility and safety of pedestrians crossing the road.
“We did contact the organisers of the event to give them the opportunity to move their signs from the safety railings, which is not something we would usually do, but were left with no option but to remove them ourselves.
“We would be more than happy to discuss directly with the organisers of Eastbourne Pride alternative locations where the signs can be posted.”Thought so!
