You become everything to all people.
In some countries to not wear a beard would be an issue.
In another the gentlemen wear clothes that might include a sarong.
Indian ladies might wear trousers. There are cultural differences.
You would always wish to respect Jehovah and wear something modest to reflect his standards. If you can see through it, down it or up it then it probable does not reflect Gods standard.
You would never ask school to alter a play or change how they worship.
Each kingdom doesn't make up their own rules, Perhaps my explanation could have been better. To what extent a bible principle is taken varies.
One person would not take dialyse and another person would. One person finds it acceptable within the principle and another does not
It is left to each persons conscience how little or how far you take that principal.
If a child is being abused you contact the police asap. No judicial review is needed to do so. The law has been broken and they answer to the law of the land.
You might sort out a minor issue around business perhaps between yourselves first perhaps, but again if it is fraud or theft rather than a misunderstanding you refer it to the Police. Some would refer it more slower than others and make more attempts to sort the problem.
So some difference in the execution of the principle.
Entertainment should be wholesome and one person might view a film another would not. There is personal choice and even with non JW some films do not appeal to everyone.
Did everyone read or watch 50 shades of grey? It just didn't appeal to everyone for whatever reason.
Hope that helps
