there is also evidence that same sex marriage was legal in medieval Europe too<quoted text>
1.) Let me prove it by saying that same-sex unions/marriages would not need to be outlawed if the they weren't taking place on a wide scale basis.
What I am suggesting is that same-sex unions "existed and continued until Christianity became the official religion of the Roman Empire. A law in the Theodosian Code was issued in 342 AD by the Christian emperors Constantius II and Constans, which prohibited same-sex marriage in ancient Rome and ordered that those who were so married were to be executed."
"(In) Mesopotamia, where documents exist for a variety of marital practices, including male lovers of kings and polyandry. None of the recorded laws of Mesopotamia, including the Code of Hammurabi, contain restrictions against same-sex unions despite the fact that marriages are otherwise well regulated."
The Mesopotamian empire lasted around 4800 years.
Is that a long enough time frame for you?
Western Civilization is said to have began around the 8th century BC. The Roman Empire started long before that time. Same-sex unions were a part of their society until it was outlawed in 342 AD.--a period of roughly 350 years.
So, there is adequate proof that the Western Civilization, by way of the Romans, accepted same-sex unions/marriages for a long period of time.
You might say that until Christianity became a dominant religion, same-sex behavior and unions/marriages were common. And since widespread Christianity is only about 1700 years old--a drop in the bucket compared to the history of mankind--the notion of same-sex behavior and/or same-sex unions/marriages being abhorrent is relatively new.
Thankfully, modern man has started to question early Christian teachings and beliefs about same-sex attractions.
We are no longer shackled to ancient belief systems based on ancient religious ideas.
As with many other current social ideas and values that we embrace, such as the eradication of slavery, racial inequality, and gender inequality, we base our notions of equality on contemporary science and ideas--not religious dogma.
Bottom line, we do not need to rely on how Christian history has treated homosexuals to determine how we treat homosexuals today.
2.) Conjugal relations refer to sexual relations between spouses. In the states and countries that recognize same-sex marriage, a conjugal relation refers to sexual relationships between a married man and a woman, a married man and a man or a married woman and a woman.
3.) The only way to have equal legal rights and protections of marriage to same-sex couples is to DENY them to all married couples or EXTEND them to all married couples--be they opposite-gender or same-gender couples.
