All sin is abhorent but there are catagories of sin. There are mortal sins (big sins) and venial sins (little sins) and there is the “unforgiveable” sin against the Holy Spirit. Not only does unrepentent homosexuality make God want to vomit so does abortion.
You seem to refer to this "sin category" thing as some-type of fact, which means it would have to have its source in scripture.
Please direct me to the Bible verses where those "sin categories" are listed.
