Hot Coffee was Rockstar's attempt to purposely leave code in the game that wasn't found for 6 months on the Playstation/Xbox, but was found in 2 days on the PC. They knew people were going to find it and "turn it on". It's just asking for some right wing/left wing nutjob group to get it's panties in a uproar and go all Fox News about it.
