Hypocrisy

Not too long ago I saw a young mother post on facebook how she wasn’t for gay marriage because it isn’t part of her beliefs. I am not gay, however I am a Christian and I do support gay marriage. Her beliefs would fall into biblical passages which state same sex marriage is against God. The young mother is 20 years old and has a two year old daughter. The biblical passage ALSO states it is a sin to have premarital sex. Because it is accepted in society, she may find nothing is morally wrong with premarital sex or even unloving sex. If two people love eachother, why can’t society accept it? There is nothing wrong with gay marriage!
