humans understand the advantages of modern traditions 
but humans have difficulties communicating with each other 
during modern traditions 
in modern traditions it's illegal for a husband to beat his wife 
both men and women understand the advantages of that 
women don't want to be beaten 
and men don't want their sisters and mothers to be beaten 
but before during old traditions 
when it was legal for a husband to beat his wife 
then his wife had an excuse to be nice to him 
because if a wife would be asked why she was nice to her husband 
then she would say that she had to 
or else he would beat her 
and that would enable her to hide her love to him 
and a wife that publicly shows her love to her husband 
will have difficulties using social defence to protect her husband 
and her family
if a wife would be asked why she sucked her husbands cock 
then she would explain that she had to 
or else he would become irritated and beat her 
and if a wife would be asked why she let her husband fuck her ass 
like she was a whore 
then she would say that she had to 
because him beating her is more painful 
because during old traditions 
if a wife said that she wants to suck her husbands cock 
then she would be considered  to be a whore 
and if a wife said that she wants her husband to fuck her ass 
then she would be considered  to be a dirty whore 
and that would decrease her social status too much 
and a wife with low social 
will have difficulties to use social defence to protect her family 
and her husband 
humans have evolved during many hundreds of thousands of years 
and have developed ways of communicating with each other 
during that time 
but modern traditions have only existed for a few decades 
and humans have yet not been able 
to develop ways of communicating to each other 
during the circumstances of modern traditions
