A Florida teen's arrest and expulsion from high school over a lesbian relationship was motivated by anti-gay animus, parents claim.

According to an account posted on Facebook by the teen's mom, Kate Hunt began dating a female student 3 years younger than herself at the start of the year when she was 17.

Kelly Hunt Smith wrote that “it was a mutual consenting relationship on both parts.”

In February, after Hunt turned 18, her girlfriend's parents pressed charges against her. Police arrested Hunt and charged her with the felony of “sexual battery on a person 12-16 years old.”

“The police came to our home and arrested my daughter, put her in hand cuffs and we had no idea why. They refused to tell us anything at first because she had turned 18. Kate was ripped out of our arms, terrified, crying hysterically.

After officials at Sebastian River High School refused to expel Hunt, the parents appealed to the school board and had her expelled.

In an online petition, Hunt's parents said they believed the parents were acting out of anti-gay animus.

Florida's consent law is not hard and fast. While the age of consent is 18, the law allows for close in age exemptions, in some cases by as much as 7 years. For instance, the law permits a person 23 years of age or younger to engage in legal sexual activity with a minor aged 16 or 17.
