Chick-fil-A said Monday that it had stopped making charitable donations to the Salvation Army and the Fellowship of Christian Athletes, groups that have been widely criticized by advocates for lesbian, bisexual, gay and transgender rights.  The fast-food chain, a longtime target of LGBTQ rights groups because of its stance on same-sex marriage, has met resistance in recent months as it has looked to expand in the United States and other countries.  Equal rights advocates described Chick-fil-A’s decision to stop funding the charities as a positive step, but called on the chain to do more.
