If I say to you, "I am gay." In what way is that vulgar? How have I committed a social misstep?
Making a statement about one's orientation is not an example of "letting it all hang out".
Maybe you long for the day, just like many LGBT people, when it's unnecessary to "come out".
As it is now, people assume that you're straight until you correct them.
Parents assume that they have heterosexual kids, yet we know that babies are being born this very second who are gay.
Like it or not, we live during a time when it is important to make ourselves known to larger society so that they no longer feel that it is OK to oppress and vilify gay people.
If we are going to live the happy lives that we are entitled to live, then we need to be sure that discrimination, ignorance, and hatred becomes a thing of the past.
You threw out several verses from scripture. I'm not sure of each one's intent.
However, I will respond to the last one; the one that mentions Sodom.
Why is it that you continue to believe that the sin of Sodom was homosexuality? Ezekiel 16:49 "Now this was the sin of your sister Sodom: She and her daughters were arrogant, overfed and unconcerned; they did not help the poor and needy."
You propagate a myth when you associate homosexuality with the citizens of Sodom. Look at the story of how Lot dealt with the supposed gang of gay men who stood outside of his home and demanded that the angels be sent out so they could "rape" them.
Lot refused. Instead he offered is daughters.
Why would Lot believe that a group of gay men would be satisfied with women? It doesn't make sense does it?
And what does it say about Lot that he would offer his daughters to be raped? What kind of father would do such a thing?
And a little bit of reading about Lot's daughters show that they were a fairly twisted group themselves. They were worried that their father's lineage was going to end. So two of the daughters got him drunk, had sex with him, and became pregnant.
Why is that story not as outrageous to you as the myth about homosexuality?
Yes. I agree. Judging the worth of a man by his exploits in the bedroom - or in today's post 60s 70s era form, in the public square - rather than by what is written in his heart is in its most elemental form rebelling against he who made them male and female. According to the instruction manual:
"Thus saith the LORD; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD." (Jeremiah 17:5)
"Blessed is the man that trusteth in the LORD, and whose hope the LORD is." (Jeremiah 17:7)
"The heart is deceitful above all things, and desperately wicked: who can know it?" (Jeremiah 17:9)
"I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings." (Jeremiah 17:10)
