As a declared Christian you should be also aware that bigotry and hatred are sins too, and they drive the person who hates from salvation much more than someone else's "disordered" behaviour. If you're declaring yourself as a Christian, your duty is not to fight someone else's perceived sins - this directly contradicts Christ's teaching - your duty is love your neighbour (Mark 12:31) and support them in getting their lilfe right, if they are in the sin, but not judging or hating.
