Moscow (CNN) -- An international backlash against Russia's anti-gay propaganda law is gathering speed, from calls for a boycott of the 2014 Winter Olympics in Russia to gay bars in Los Angeles planning "vodka-dumping" protests.
A number of bars worldwide have also stopped serving Russian vodka to protest Russia's stance on homosexuality.
The furor follows concern sparked by the Russian Parliament's overwhelming support for a new law banning "propaganda of nontraditional sexual relations around minors."
Implemented last month, after President Vladimir Putin signed it into law, it bars the public discussion of gay rights and relationships anywhere children might hear it -- and has been condemned by Russian and international rights groups as highly discriminatory.
