Whatever... You can call them whatever you want.
Jesus wouldnt call a homosexual a sub-human.
This boy never claimed to Jesus. Do you disagree that Jesus woould call them sinners or evil doers? I dont. If you practice and encourage evil then you are evil - subhuman is to good of a word to use - animals should be offended by the term because even they dont revert homo sex. Putting your penis in the poopoo is unnatural - I assume his reference for the use of the term subhuman.
Actually you are correct. He would call them an abomination like his Father did. (That's not saying that he wouldn't give them a chnace to repent and be saved however)
