Are Slavery, Racism, Sexism, etc. "Judeo-Christian Values"?

People have said that "America was founded on Judeo-Christian values". Okay, let's say this is true.

Slavery existed at the time when the country was founded and well instituted into the 19th century.

Racism, which still exists today, became a way of life and institution at the time the country was founded. The most racially segregated hour in America is Sunday every week when church services are conducted.

Sexism, such as women not being to vote until the early part of the 20th century was institutionalized when the country was founded.

So it begs the question: should we be afraid of any resurgence of Judeo-Christian values in America?

Kinda of a sarcastic question to those silly Islamophobes who fear "Islamic values" taking root in their society.

Touche!
