Jakub Cupriak -Trojan, an Equality March participant in Poland - June, Warsaw 2018. He`s holding the rainbow flag as a symbol of him belonging to the LGBT community. He's also wearing a T-shirt with the Polish word for "constitution" on it. The original version of this sign (without a rainbow, designed by Luka Rayski) was commonly used during the mass protests against the Polish government breaking the law written in the Constitution. By adding the rainbow, Jakub signalizes that he's on the protesters' side, and emphasizes on the fact that the rights of the LGBT community in Poland aren't respected and protected by Polish government.
