Gay conversion therapy, the controversial practice aimed at making gay people straight, may be banned for minors in Seattle thanks to a new proposed ordinance on Tuesday.

The proposed ordinance was approved by the Seattle City Council and must be adopted by the entire City Council before going into effect.

Gay conversion therapy for minors is banned in California, New Jersey, Oregon, Illinois, Vermont and the District of Columbia. 

Seattle may join Cincinnati, the first city to put such a ban in place.

“It’s absolutely offensive to me, that instead of providing these children, who are going through perhaps a moment of confusion … instead of providing them the support that they need, there are people out there who believe it’s appropriate to convince these children that their same-sex orientation is somehow a disease, or an illness, or something that can be cured. And I think that that does a disservice,” said Seattle Councilmember Lorena Gonzalez, according to KIRO 7 News.

Violating the ordinance would be punishable with a $500 fine for the first offense and $1,000 for subsequent offenses.

Advertising conversion therapy for minors is subject to a $300 and/or 90 days imprisonment for false and deceptive advertising, a misdemeanor.

The final adoption is scheduled to be considered on Monday at 2 p.m.
