Why LGBT exists?

Why LGBT exists? (Romans 1) ...THEY CLAIMED TO BE WISE ...and exchanged the glory of the immortal God for images made to look like a mortal human being... ...THEY EXCHANGED THE TRUTH about God for a lie and worshiped and served created things ( themselves) rather than the Creator... ...THEY DID NOT THINK IT WORTHWHILE TO RETAIN THE KNOWLEDGE OF GOD... In today's words....THEY BELIEVE IN "FREEDOM" to do their will to define good and evil in their own eyes for their self justified desires.
