Not sure if huffpost is a site you would consider trustworthy, but anytime you search for Che and the gay community, its quite consistent with the fact he rounded up the gay and other queer people and had them tortured, raped, and killed.
Look I don't doubt your commitment to allying with the queer community, but throughout the history of communism, the queer community has also been persecuted by the likes of the Soviet Union, Cuba, hell even China today. Forgive me if my biggest hang up with the communist label are the regimes and people it's associated with, what they did to people like us.
Do you have anything against these reports though? I can give them a read.
