By definition, all sex outside the construct of marriage is considered fornication, and fornication is sin.
And what is marriage?
4 And he (Jesus) answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female,
5 And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? 6 Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder (Matthew 19:4-6).
Therefore given that sex outside of marriage is sin, and marriage is defined by Jesus as one man and one woman, we can conclude that homosexuality is sin.
Further it is written, "9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God (1 Corinthians 6:9-10).
Notice the list doesn't single out homosexual behavior. There are a variety of sinful behavior that disqualifies a person from the kingdom of God. The reason homosexuality is often vocally targeted by Christians is because society is seeking to [and now has] legalize it. If society wanted to legalize theft or extortion and I spoke against it, would you consider me a bigot towards thieves and extortionists?

If it could be proven beyond doubt that God exists...
and that He is the one spoken of in the Bible...
would you repent of your sins and place your faith in Jesus Christ?
