Caroline Farrow, the UK campaign director of CitizenGo was en route to Orlando when she had her previously approved Electronic System for Travel Authorisation (ESTA) revoked at the airport on Tuesday.
CitizenGo is an advocacy group that promotes petitions including those that oppose same-sex marriage, abortion, and euthanasia.
According to LifeNews, Farrow was visiting Florida to hand-deliver a petition, signed by nearly 500,000 people to Disney World, calling for the park's gay pride parade to be cancelled to protect children from "LGBT indoctrination".
Farrow has speculated her refusal into the country may be the result of hate crime reports made to the US Embassy.
On Twitter she posted: " It therefore looks like having discovered that I am going to the US, 2 people file a police complaint last week, tip off the embassy or Homeland security and my ESTA is revoked.
"The vindictive obsessive mentality is quite something to behold.

The vindictive obsessive mentality is quite something to behold.
Farrow's concerns come after comments she made about gender-transition procedures for children sparked months of harassment from online transgender activists, including the publishing of photographs of her children's school.
Dr. Adrian Harrop, a vocal critic of Farrow hinted involvement on Tuesday, after saying he had attended the American Embassy in London: "An absolutely spectacular building... and one of London's great modern embassies... but honestly, I always did prefer the retro and kitsch qualities of Grosvenor Square... as always, consular staff very efficient at dealing with my... important diplomatic business."
Another twitter user opposed to her views wrote: "Anyone know somewhere warm/sunny this time of year? Is Florida nice?"
"It mustn't be anywhere that being linked to a psycho right-wing extremist organisation will deny you entry to. Because people can make representations about such things. Apparently," he continued.
