A lot of the treatment of homosexuals by biblical conservatives is dependent on the context. The university is an interesting place because it's neither church nor regular community, but rather some sort of combination of the two. In a community biblically conservative Christians would seek to love their neighbors and treat them well to bring Christian love into the community and ultimately to spread the gospel and bring people into the church. The goal isn't to get their neighbor to stop some particular activity in particular, but to bring them to the point of repentence for all their sins so they might be forgiven and enjoy fellowship with God and fellow believers. Once within the church there is an expectation that members will refrain from unrepentant sin. Church members hold eachother accountable and ultimately anyone who continues in unrepentant sin is subject to expulsion. This is a messy business and should be approached with all humility, but there are countless examples of it being done in a poor manner. But, there are also examples of marriages being saved and people giving up self-destructive behaviors because of this accountability mechanism. At the end of the day the only people who are held accountable are the people who commit to being held accountable.
