Marriage is deceit. It is wrong and demeaning because when we only do what we want we cannot really mean to be with or at least tied to a person forever no matter what. There is no marriage for the vows are insincere. You cannot say you want to be with somebody for your whole life for you do not know what changes will come upon the other person.
Marital union is not even necessary to our welfare so it is unjustifiable. There is nothing that marriage can do that some other arrangement can't do just as well. Love is just a euphemism for lust, the selfish desire to gratify yourself with another person. If it were not then we would be falling for people no matter what they looked like and love is triggered by the qualities in a person secondarily after physical appearance so it is just these you are after and not the person. Marriage, one person giving themselves to another forever, has to be exposed because this giving is not genuine for it is dependent on a changeable feeling.
Marriage vows don't bind until the couple have sex. So they are tied together because of one sex act. That clearly proves what a humiliating superstition marriage is. The wife is sold to the husband by sex. She is his because she gave him her body once. That is prostitution and to use women that way is appalling.
Marriage implies that divorce and even a legal separation is wrong for it says that even a wife who leaves a violent husband to avoid being beaten to death still has no right to have sex with anyone except her husband. To say otherwise would be saying the marriage was no more. When the husband has the right to her body which is the most important thing she has, she cannot have the right to divorce him because her right to be happy with another man is less important than the right of the husband over her body. To ban divorce and separation would be the utmost assault on her dignity and assuring her subjection to patriarchy. Marriage then is worrying and is not about two equals sharing their lives together but is meant to be about the one half deceiving and exploiting the other half.
Marriage is not for making sure a man and woman stay together because marriage is still encouraged in cultures that make it easy to get out of via divorce. The idea that it is the intention that counts is silly for intentions change and you can't make a man and woman behave like husband and wife because they had the intention to be together forever at a special moment in time namely during a wedding ceremony.
Marriage is getting the permission of society and the Church to have sex and they need only have it once for one sex act consumes the marriage and makes it valid and official. The bride and groom only debase themselves by getting married. It is superstition and not an act of love and it is none of society's business about the sex. They are bound together by a sex act and not their commitment. People may say they got married because they wanted to and seeking permission from society to have sex and nothing to do with it. Then they don’t understand marriage – they think it’s a romantic day out for it means nothing without the laws and permissions of the Church or society or both. Marriage involves authorised people telling you that you have given yourself to your spouse and now belong to her or him so it is about permission to have sex for you already belong in love and it implies that sex without this permission is evil.
Marriage implies that you should only sleep with your wife or husband for life for why have marriage and not an alternative if you may sleep around? Marriage is based on jealousy and lies. If you really wanted your partner to be happy you would not mind them leaving you and then meeting somebody else that makes them happier than you can. People's needs change. Jealousy is about trying to stop your partner being happier. Marriage is about power not love. Humanism will not drive people out for getting married. But marriage is dehumanisation and implies that unmarried people have no right to have safe sex together ever so it only supports the regime that teaches such bigoted nonsense.
