What evidence supports the republican belief that traditional family values were deteriorating ?

sexual revolution and birth control

Explanation: Sexual revolution was a social movement which challenged the society's traditional codes of accepted behavior related to sexuality and interpersonal relationships throughout the United States which started in the 1960s. It included increased acceptance of sex outside of traditional heterosexual and monogamous relationships.

Birth control which is also known as contraception and fertility control, is a method(which may be in form of pills or a device) used to prevent pregnancy. Conservatives generally frown on the use of birth control.

The two points above were evidence that supported the Republican belief that traditional family values were deteriorating.
