polygamy is gradually decline in our societies discuss why​

Answers

Answer:

because they feel more burden, polygamy is illegal all over the country because people face alot of difficulties.

Like Sati, polygamy was a practice used in the past to discriminate against women. Women cannot marry many men, but males may. These days, few people do this since women and men are treated equally.

What is polygamy?

The practice of having many spouses is known as polygamy. Sociologists refer to a guy having many wives at the same time as being polycystic. Polyandry is the practice of a woman being married to more than one guy simultaneously. Monogamy, in contrast to polygamy, is a marriage between just two people.

All American jurisdictions outlaw polygamy by declaring unions with more than two wives null and void. An annulment is typically required by state laws that prohibit bigamy, which is being married to someone while you are still legally married to someone else. An annulment also ends a marriage, much like divorce does. As a result of war fatalities, there was an increase in the number of single women.

What does James warn believers about?

He denounces a number of faults, such as arrogance, hypocrisy, favoritism, and slander. He exhorts and implores Christians to pray constantly and to live modestly by spiritual guidance rather than worldly understanding. The epistle of James was largely ignored until the late 20th century, despite many early theologians and intellectuals avoiding it because of its promotion of Torah adherence and good deeds.

Famously, although treating it as the infallible word of God in his Large Catechism, Luther formerly thought of the epistle as one of the contentious books and relegated it to an appendix. Due to a rise in interest in the historical accuracy of the Bible, the epistle of James has garnered more scholarly attention in recent years.

When it comes to understanding families, how are structural functionalist and conflict theoretical perspectives different? Based on what you read in the chapter, contrast how the two theories might explain the breadwinner-homemaker family

Answers

Answer:

Explanation:

The difference between these two perspectives is that Consensus Perspective projects an image of society as the collective expression of shared norms and values, while Conflict perspective is the view that opposition and conflict define a given society and are necessary for social evolution. In a breadwinner family both of these will be different.

For Consensus Perspective the breadwinner in the family would be the individual defined by society as normal, which would be the man while the woman watches over the house and kids. This is considered old-school mentality.

Conflict perspective on the other hand would oppose such societal norms and in this perspective the Woman would be the sole breadwinner of the family providing all the financial necessities that the family needs, while the Man takes care of the kids.

Why is characterizing Kagan’s view as an "atheist" view a misnomer according to him?

Answer:

Because his vision uses the appeal to God.

Explanation:

For Kagan, an atheistic view could not make use of the appeal to God, since the atheist is opposed to any measure of this deity, his deeds and the ways of reaching him. In that case, it is totally inappropriate to call his view an atheist.
