The president and co-founder of the National Organisation for Marriage will travel to France next week to participate in an anti-gay conference and training session.

NOM’s Brian Brown will attend La Manif Pour Tous’ Summer University Training Session.

La Manif Pour Tous is the largest anti-LGBT organisation in France, casino formed in 2013 to protest same-sex marriage in France.

Brown will reportedly give a talk at the conference, entitled “The International Experience of Combat Against the Redefinition of Marriage”.

Last week, Brown claimed there is a “very good chance” that the US Supreme Court will uphold bans on same-sex marriage.

Earlier this summer, Brown compared “redefining marriage” to calling a table a “chair”.
