Because Tony Perkins and his ilk aren't happy unless LGBT citizens are kept sick, oppressed, and alone, the FRC is upset that gays are signing up for Obamacare. Reacting to the Out2Enroll campaign, an independent movement targeting the disproportionately uninsured LGBT community, Tony Perkins launched into a rant about how "a high risk pool fed by even higher risk behavior" would destroy the medical care system due to the increased medical demand. Perhaps it's somewhat comforting to know that it's not just the "cross-dressing men" who he thinks aren't deserving of health care, but everyone who isn't already a young, healthy individual. Perkins said in part:
As taxpayers are about to find out, the system wasn't designed to withstand the volume of elderly, sick, and at-risk patients most likely to enroll. Either the exchanges will buckle under the weight or the government (i.e. taxpayers) will start shouldering even higher costs to compensate for the medical demand.
So in short, anyone who needs health care insurance is a drain on the system for the healthy people who evidently need it more.
