Harmless Hugs organised the first LGBT Flashmob in Delhi in 2015 and have been doing it every year since then. Skudlarek.Harmless Hugs was started as an online secret LGBT group and took shape of a young collective which is working for LGBT rights in India. Updated for the March 2005įfihugs changes by Joseph P. Updated for Hugs 98īy Antti-Juhani Kaijanaho and Ross Paterson. (with apologies to the original authors) by Mark Jones.
