President Barack Obama ridiculed Republican fear mongering of his signature health care law on Thursday, five days before its insurance exchanges are set to open, pointing out that many things lawmakers said about Obamacare never actually came true.

“One congressman said that Obamacare is the most dangerous piece of legislation ever passed,” Obama said in Largo, Md. “Ever, in the history of America, this is the most dangerous piece of legislation. Providing — creating a marketplace so people can buy group insurance plan, the most dangerous ever.”

“You had a state representative somewhere say that it’s as destructive to personal and individual liberty as the Fugitive Slave Act,” he added. “Think about that. Affordable health care is worse than a law that lets slave owners get their runaway slaves back. I mean, these are quotes. I’m not making this stuff up.”

“And here’s one more that I’ve heard. I like this one. We have to, and I’m quoting here, we have to repeal this failure before it literally kills women, kills children, kills senior citizens,” an incredulous Obama said. “Now, I have to say, that one was from six months ago. I just want to point out we still have women, we still have children, we still have senior citizens. All this would be funny if it wasn’t so crazy.”
