Baltic Pride is an annual LGBT pride parade rotating in turn between the capitals of the Baltic states; Tallinn, Riga and Vilnius. It is held in support of raising issues of tolerance and the rights of LGBT community and is supported by ILGA-Europe. Since 2009 the main organisers have been Mozaīka, the National LGBT Rights Organization LGL Lithuanian Gay League, and the Estonian LGBT Association.
Baltic Pride is supported by the National LGBT Rights Organization.
The National LGBT Rights Organization are a main organizer not the main supporter. The main supporter is ILGA-Europe. I think that the system got this one wrong due to the complexity of what I wrote.
