Okay, where do your moral absolutes come from? The Bhagavad Gita, Mahabharat, or other Vedic scriptures? Hmmm, that won't work. They have the same basic moral absolutes. Okay, do yours come from the Torah and the Talmud? Hmmm, that won't work, the Torah is part of the Bible and the Talmud agrees with it. Okay, Buddhist teachings and moral absolutes? No, that won't work either, they have the same basic moral absolutes. Okay, Sikh dharma - ooops, same moral absolutes. Jainism? Nope, same moral absolutes.
Okay, where do yours come from? Your mind? But other peoples' minds think up different sets of right and wrong. Guess what - other than the religions of the world (which all agree on the basics) there is no source of moral absolutes in the history of the world.
Okay, people have devised morals without the light of religion. But these "morals" often say that sex with members of your own sex is fine, sex outside of marriage is fine, abortion is fine, and so on. Philosophies such as Nazism considered itself very moral - Killing all the Jews wasn't called the Final Abomination, it was called the Final Solution! Hitler and his assistants were just trying to make the world a better place, according to their view of right and wrong.
In fact, although such things may be illegal at the present moment, bestiality, necrophilia, incest, and "intergenerational sex" all have their promoters, backers and supporters. Just saying that these practices are at present illegal is meaningless. Same sex sodomy was illegal in many states until the Texas vs Lawrence decision.
They didn't need the text of a Bible to understand morality.
This statement of yours is either made out of total ignorance of history, or a desire to misrepresent history. Are you a liberal revisionist history teacher by any chance? Here's a few quotes for your edification.
"We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge, or gallantry [18th century word for illicit sexual relations], would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other." John Adams
"The highest glory of the American Revolution was this; it connected in one indissoluble bond the principles of civil government with the principles of Christianity." John Quincy Adams
"It is the duty of all Nations to acknowledge the providence of Almighty God, to obey his will, to be grateful for his benefits, and humbly to implore his protection and favors." --George Washington
"It is impossible that a nation of infidels or idolaters should be a nation of free men. It is when a people forget God that tyrants forge their chains. A vitiated state of morals, a corrupted public conscience, are incompatible with freedom." --Patrick Henry
"Before any man can be considered as a member of Civil Society, he must be considered as a subject of the Governor of the Universe." --James Madison
“We have staked the future of all of our political institutions upon the capacity of mankind for self-government, upon the capacity of each and all of us ... to sustain ourselves according to the Ten Commandments of God.” -James Madison
[O]nly a virtuous people are capable of freedom. As nations become corrupt and vicious, they have more need of masters." Benjamin Franklin
"By removing the Bible from schools we would be wasting so much time and money in punishing criminals and so little pains to prevent crime. Take the Bible out of our schools and there would be an explosion in crime." Benjamin Rush
"Reading, reflection and time have convinced me that the interests of society require the observation of those moral precepts ... in which all religions agree." --Thomas Jefferson
I would also take a moment to remind you that because of Lawrence v. Texas gay sex is legal in all states now, so that isn't a valid excuse to ban pro-gay clubs.
Even if same sex sodomy is legal (because of a very stupid SCOTUS decision) why should sexuality be a basis for a club in public schools? There is simply no legitimate reason to promote dangerous sexual behavior in schools - a behavior which the majority of the American people do not consider moral.
My question to you is this: Why do you want to promote the "gay" agenda?
BTTT
Why shouldn't it? If a bunch of girls wanted to start a "Susie Homemakers' Club" where they would plan to snag a man and raise a family, would you want the club banned? Why two different standards, one for pro-heterosexual and one for pro-homosexual clubs?
