That's what they said about Jesus too because He refused to be a member of the herd. His teachings were extremely radical for His time and culture. For some reason you want to cling to all the crap along with the gems, whereas I wish to cull the gems from the crap and let the crap go down the drain of history.
We know better now than to stone women who are not virgins on their marriage beds, not to have slaves, not to sell children, not to take women as spoils of war, not to torture mentally ill people to drive out demons, not to persecute left-handed people, not to stigmatize crippled people or people with birth defects (unless they happen to be transsexuals--and then it's still acceptable), not to deny women equality, not to condemn interfaith or interracial marriages, not to stigmatize women while they are having their period, not to worry about mixing fibers in clothes or crops in fields, we stopped labeling foods as unclean (like pigs and shellfish), but with all our advancements we still have this taboo about being homosexual despite all the scientific evidence that points to it being a non-issue.
Loving others as yourself can hardly be expressed by disenfranchisement, stigmatization, and denial of legal equality against people who are doing no harm.
