For a clued up, long standing in good faith JW to support worldly charities is just not on.If the person is a JW , he is either new , mentally unbalanced ,( no offence it happens ) or whatever else you come up with , but he is not representative of JW`s. as a whole.
Think about it ,JW`s teach that only Gods Kingdom is going to fix mankinds woes.Nobody else.
That the whole world is lying in the power of the wicked one Satan the Devil , if you support any of the worlds programs you are supporting Satan , especially in this time of the end.
You cannot be slaves to two masters , etc , etc, .
And if a JW was giving his time and money to further a worldly charitable organization a part of Satans System of things , instead of giving that time and money to the WTB&TS he or she would be brought before a JC to please explain.
And as another poster explained JW`s charities for what they are only benefit JW`s or their family or friends , not the general public , as is usual in theses cases .
