From the article this is based on:
“There is a very good chance (but no certainty) that at least one lethal GRB took place during the past 5 Gyr close enough to Earth as to significantly damage life. There is a 50% chance that such a lethal GRB took place during the last 500 Myr causing one of the major mass extinction events.”
“Lethal” is defined as “life-threatening (lethal) GRB”. It does not mean to kill every living thing, only able to kill something.
The ICR article says this:
“Two astronomers, Hebrew University of Jerusalem’s Tsvi Piran and University of Barcelona’s Raul Jimenez, found that GRBs should have repeatedly sterilized most places in the universe, every so often annihilating any chemical concoction that may have been headed toward life. The new report appears in the online repository arXiv.org.2”
The article by the astronomers says nothing like that.

They get really angry when you point out their logic flaws and misdirection (ICR=Institute for Creative wRiting). Better to play along...
