Once again, there are confused ignoramuses who mistake the legal secular definition of marriage (hetero & homo unions) with the religious definition of marriage, otherwise known as "MATRIMONY".
The US Supreme Court left MATRIMONY ALONE & IS NOT TELLING THE CATHOLIC BELIEVERS WHAT TO THINK!! It is just reminding them that their behavior can't be discriminatory under the guise of religious practise... they ought to practise the tolerance towards people that Jesus Christ modeled throughout his life...
