Activists rallied Sunday in Paris to demand that the French government abandon a bill aimed at rooting out Islamist extremism that the protesters say could trample on religious freedom and make all Muslims into potential suspects

French lawmakers hold a key vote Tuesday on the draft law, which is expected to win approval in both houses of parliament. The legislative debate comes amid lingering fears of extremist violence after an Islamic radical beheaded a history teacher and other recent attacks.

President Emmanuel Macron’s centrist government argues that the bill is needed to protect French values like gender equality and secularism, and to prevent radical ideas from taking root and inspiring violence.
