far be it for a leader to seek the moral good of a country, it's none of his/her business if the nation embraces lewd and lascivious lifestyles.
In a liberal democracy, no.
In a theocracy, yes.
then maybe our "leaders" shouldn't advise kids to stay in school and work hard and become good and honest members of society
They have nothing to do with 'morality' - let alone a 'Christian' value.
I know plenty of people who would fall under your categorisation of 'lewd and lascivious lifestyles (gay, sexually confident, occasional drug use etc etc...) ' - who have worked hard, stayed in school, graduated University and are good, decent and honest members of society... who pay taxes, do not harm others etc etc...
Being a productive member of society and adhering to 'Christian Morality' are not one in the same... to you they are perhaps...
