On the 41st anniversary of Roe v. Wade, Fox News Political Analyst Brit Hume delivered a passionate commentary on abortion – a broadcast that has gone viral.

Hume praised the commitment of those attending the March for Life each year and accused abortion supporters of resorting to “absurd euphemisms” to justify their position.

“Science has given us an ever-clearer picture of just how much of a baby a fetus is. At 20 weeks, we now know these tiny creatures can hear, even recognize a mother’s voice,” Hume said. “Their toe nails are growing and their hearts beat loud enough to be heard  by a stethoscope.”

Hume blasted Planned Parenthood, citing their announcement that they carried out 329, 445 abortion procedures in 2012 alone.

He continued by suggesting that the moral case for abortion grows weaker every day and pointed to the case of abortionist Dr. Kermit Gosnell, who is now serving a life sentence for the murder of a baby born alive in a botched abortion, among other acts.

“If science is able to determine that a fetus at a certain age, a certain stage, feels pain … that would change everything,” said Hume. “I think that support for abortion and abortion rights and for its legality would crumble…and the political atmosphere around this issue would change almost overnight.”
