Christianity is a weight dragging all of society down with it

Before I start, sorry the title was a little vague, but I'll stick with it. I believe that Christianity is a (metaphorical) weight dragging society down with it for several reasons. Firstly, when I say 'all of society', I did literally mean all of the people in society (USA and UK). This is purely because there are Christian people scattered all around theses countries and even though not everyone is Christian, the tremendous majority of people are influenced by Christian beliefs, or live in a society where Christian beliefs are dominant. Secondly, I believe that the bible plays a major part in dragging down society. This is because of its sexist and homophobic views on life, which were obviously socially acceptable 3500 years ago, but to stick by these abhorrently exclusive social 'rules' now, is a crime against humanity, and results in people physically living in the 21st century, but mentally living 3500 years ago with extremely narrow-minded views, and all that's left to back that up is 'God said it'. It is clear that the bible is extremely sexist towards women, and there are excessive amounts of quotes I could bore you with, but I'll only use a couple: "Women should remain silent in the churches. They are not allowed to speak, but must be in submission, as the law says" (1 Corinthians 14:34), "Wives, submit yourselves to your own husbands as you do to the Lord." (Ephesians 5:22), and finally; "woman is the glory of man." (1 Corinthians 11:7). All these quotes highlight the fact that times were very different when these books were written, and that there was tremendous gender inequality, however, times have changed, with both genders being treated more equally in everyday life, and men not seen as superior or having power over women, but they are both equal in their relationship (in most cases). Therefore the Bible does not encourage equality between genders, and sends out the completely wrong messages to Christians in modern society, and if it's doing anything, it's causing clashes and conflict. Homosexuality. It is clear that the bible is anti-gay by condemning homosexuals to death and calling their acts 'abominations': "If there is a man who lies with a male as those who lie with a woman, both of them have committed a detestable act; they shall surely be put to death. Their bloodguiltness is upon them." (Leviticus 20:13), "You shall not lie with a male as one lies with a female; it is an abomination." (Leviticus 18:22). I would say that society has, mainly, accepted homosexuality as a natural thing, as it happens all around us in the animal kingdom, it was the norm in Ancient Greek society, and many people are revealing their love for the same sex, and by the bible encouraging such hurtful things, conflicts are caused in modern society when most people have already accepted homosexuality. I do understand that there are some upsides to Christianity's teachings; such as the Ten Commandments and the other general morals that are preached and constantly drilled into your head. "Thou shalt not kill" is a reasonable one because it inflicts harm on a person and steals their life: which is not yours to take. "Thou shalt not commit adultery" again, this has fairly obvious reasoning behind it; adultery inflicts emotional harm on the victim and provokes jealousy and hatred. I think you'll agree that the reasons behind these morals are pretty plain, however the reasoning behind "If there is a man who lies with a male as those who lie with a woman, both of them have committed a detestable act; they shall surely be put to death. Their bloodguiltness is upon them." is fairly vague and obscure since no harm is caused in these homosexual acts and both participants are willing, and also what good does condemning gay people do? Condemning murderers prevent the intentional ending of another's life, condemning adulterers prevents some emotional harm in the world, so what good does condemning gay people do? The obvious morals taught by the bible do have an upside, however even without Christianity we would still be taught these morals in schools, work life and by parents; purely because they are blindingly obvious. So there is an upside to Christianity. But without Christianity that upside would still exist.
