A Russian lawmaker has proposed a bill that would define gay men and lesbians as unfit to parent.

According to the AP, a draft of the bill was posted Thursday on parliament's website.

It would make the “fact of nontraditional sexual orientation” a basis for denying custody. Alcoholism, drug use and abuse are other grounds listed.

Introduction of the bill comes at an awkward time for Russia. Passage of a “gay propaganda” law which prohibits the public promotion of gay rights among minors has provoked worldwide protests and calls for a boycott of the upcoming Winter Olympics to be held in Sochi.

Alexei Zhuravlev, a member of the lower house of parliament and the bill's author, said that “gay propaganda” had to be banned not only in the public space “but also in the family.”
