Parades celebrating LGBTQ pride kick off in some of America's biggest cities Sunday amid new fears about the potential erosion of freedoms won through decades of activism. The annual marches in New York, San Francisco, Chicago and elsewhere take place just two days after one conservative justice on the Supreme Court signaled, in a ruling on abortion, that the court should reconsider the right to same-sex marriage recognized in 2015.
