most probably it's a typo for 'barbarically' (=barbarisch).
I think this is a famous quote by Christopher Hitchens:
“Many religions now come before us with ingratiating smirks and outspread hands, like an unctuous merchant in a bazaar. They offer consolation and solidarity and uplift, competing as they do in a marketplace. But we have a right to remember how barbarically they behaved when they were strong and were making an offer that people could not refuse.”
