I have no problem with private rules and regulations. The Constitution is to structure and limit government. However, government has taken the stance that for select groups the Constitution will limit private individuals and business as if they are government.
This is where things get sticky:
1. Civil Rights have been including gender, age, race, and religion. They have been expanded to ethnicity, and sexual preference;
2. The First Amendment is clashing with ... damn ... the First Amendment (speech vs. speech), and the First Amendment (religious regulation) vs. whatever I want to be sexually.
Who's protections count here?
Here we go, Phil can show you the Bible he quoted. Can you show me the gene that makes you the sexual orientation just like the gene that makes you male, female, black, white or green?
