what does the Bible say about Homosexuality?

I've heard many people tell me that being gay isn't wrong and that the Bible says nothing against Homosexuality. I've actually had a lady tell me that the verses in Leviticus are mistranslated. That the verse really means “a man shall not lay with a boy”. So I checked this out in the Hebrew translation of the Bible and it still says a man shall not lie with another man. Hating gay people is wrong. But it’s just as wrong to not hate the sin of Homosexuality. I always say that you should love the sinner, but hate the sin. Many Christians are just so happy to blend in that they forget what’s most important. If you disagree with me please feel free to tell me so in a calm and collected way. And If you wanna change my mind than I’m open to your explanation for why you think I’m wrong. I hope you enjoy this short video of me talking about this and bringing up a few verses. I probably shouldn’t have used the NIV, as that is not my favorite translation, but in this case the verses had essentially the same message.
