A conservative group in Indiana warns in a flier distributed to churches that schoolchildren would be harmed if Indiana does not ban gay marriage.

Advance America's flier includes “four dangers of same-sex marriage.”

“Beginning in kindergarten, schools would be required to teach children that homosexual marriages are normal and acceptable and the same as heterosexual marriages,” the flier states.

“It is part of the homosexual agenda,” Advance America founder Eric Miller told ABC affiliate RTV6.

Other dangers include the prosecution of clergy members, allowing “men who dress as women” legal access to women's restrooms, and fines for Christian businesses that refuse to serve gay couples.

The flier urges voters to call their legislators and ask them to vote for HJR-6, the proposed constitutional amendment which would prohibit the state from recognizing any union other than a heterosexual marriage. A needed second vote before heading to voters in November is expected to take place early next year.

Jennifer Drobac, a family law professor at the Indiana University McKinney School of Law, criticized the flier.

“This flier is designed to demonize and make same-sex couples less worthy than other couples,” Drobac said. “It is designed to put fear into the hearts and minds of Hoosiers so they would vote against the civil rights of same-sex couples and their families.”
