Religious vs gay rights

I am interested in resources and articles (especially of a more intellectually rigorous sort) on how the rights of the religious are supposedly being infringed when it comes to rights for homosexuals. e.g. Christian B&B owners being told they cannot deny homosexual couples a double room, Christian adoption agencies being told they cannot discriminate against gay couples, Christian foster parents told they should not tell children under their care that homosexuality is wrong.

PS this is for an upcoming presentation I have been asked to give at a conference at Magdalen College, Oxford. April 11- 13. Religious Freedom and Equality: Emerging Conflicts in North America and Europe. Sponsored by The Religious Freedom Project, Berkley Center, Georgetown University, and The Center for the Study of Religion in Public Life, Kellogg College, University of Oxford. Link here.

I will be in discussion with Prof. John Finnis.
