Homos are guilty of more than a mere sin, they are guilty of a capital crime. (Leviticus 20:13; Romans 1:26-32). Being a homo isn't merely about a perverted sexual act. Homos erode the very fabric of the whole of society, both morally and socially via issues including but not limited to the spread of various diseases, child molestation, drug use, domestic violence, adultery, murder and suicide.

As such, Christians should not treat homos as though they've stolen a grape from the grocery store, or used a curse word in mixed company. They should be treated essentially the same way one would expect to treat a rapist or murderer.

In short, Christians should approach issues of moral crimes with the following three pronged approach.

1. Advocate the re-criminalization of such crimes as adultery and homosexuality and that such crimes should be punishable by death.

2. Impose, as much as possible, a social stigma to these behaviors.

3. Encourage repentance of individual offenders.
The order of those three points is intentional. Point one effects an entire society, point two effects the immediate circle of influence of those imposing the social stigma (usually at most a neighborhood or town) and point three effects single individuals.
