Same sex marriages are haraam in islam, it is one of the most repugnant deeds even amongst the haram deeds. to say that these marriages are frowned upon is an understaement.

To do something haram is wrong and to do something which is one of the biggest haraam is even greater wrong and then to have the shameless audacity to make it look islamic is nothing but to make mockery of Islam and hence I think the people indulging in such marriages and those supporting them are not fit to be called muslim
