discrimination laws, as I understand them, only apply to education, commerce, and housing.
Please tel me where these discrimination laws are that allow the government to regulate private church ceremonial services.
I'll wait.
Polygamy is one. Islam allows a man to have up to 4 wives. That is not allowed in the United States. Remember, discrimination includes treatment or consideration of, or making a distinction in favor of or against, a person or thing based on the group, class, or category to which that person or thing belongs rather than on individual merit. In this case, a person is being discriminated against because he is a Muslim, a religion which has been around for over 1,000 years.
And the Ministerial exception is treading on thin ice. Here's some background:
Ministerial exception: Title VII of the Civil Rights Act of 1964 makes it illegal to discriminate against employees because of race. But when Congress enacted that law, it carved out a "ministerial exception." This means that churches and religious organizations cannot be sued for gender, religious, national origin or racial discrimination.
