So why does homosexuality still get the brunt of believers’ hate?
Shaving (Leviticus 19:27), Cursing (Ephesians 5:4), Gossip (Leviticus 19:16), Football on Saturdays (Exodus 20:8), eating lobster (Leviticus 11:10), Eating Pork (Leviticus 11:7), Cotton/Polyester Blends (Leviticus 19:19), associating with women who are on their periods (Leviticus 15:19-20)
Because it’s also mentioned in the New Testament?
Yes, yes, and even that is questionable.
But even Jesus supposedly said, during the sermon on the mount:
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.”
(Matt 5: 17-20)
