Sally Strange commented on A renegade history of the United States by Thaddeus Russell
Really interesting section on how the Italian mafia opened gay bars during the 50s and 60s - not just because they could profit off of them but also because several prominent mafiosos such as Fat Tony, who was known to have a long-term relationship with a Chinese drag queen, were themselves queer in some way. The raid on Stonewall was instigated by the Feds because the mob had been paying NYPD to leave the bar alone.
