There is actually quite an interesting fact to note:
Homosexuality was very much accepted before State and Church merged in the twelfth century. It is an ancient phenomenom; in the Roman age it was common for individuals to have a relationship with a same sex individual next to their marriage, and homosexuality was celebrated in many forms of Art. Aother point; quite a few founding fathers of the Christian church participated in homosexual activities. Nevertheless, back to when State and Church merged; the discrimination towards homosexual began when they were protected as a minority group alongisde others, and with the breakout of Witch Hunts any non-mainstream behaviour was associated with witchcraft. Focusing on the minority group partial, I believe that protecing Transgender invidiuals under a seperate law as likewise with homosexual individuals would also have a negative effect, and therefore I can understand why some may prefer to advocate for extending little laws.
Um yeah, I did my research paper on homosexuality...
