I do not think it is very nice to call someone ignorant. And not to be rude to your family or to the memory of your father, but when my father passed away we had alot of expenses associated with his passing (medical and funeral). My father did alot of things for the community and was well though of (including by your father). But my mother and father planned ahead, bought and paid for burial/life insurance. The difference left over we (the family) paid or will pay for out of pocket. We did not ask or expect the public (or anyone else) to take on or help with the cost. Maybe that is something your father or family should have considered.
All though out this whole process I have kept my mouth shut out of respect for your family. But I can no longer continue to bite my tongue. I will now say that I know more than once your father would have his hand out asking for charitable contributions, something at a discounted price or for free. I know because he approached my father many times through out the years.
Now
YOU asked for some answers.
YOU said you wanted to hear them.
YOU opened that can of worms. So here is your answers. Do not get mad at me if you do not like the answers!
What your father did for the students of PNG was great!

But do not resort to name calling or get mad at someone else if they want to let your father's memory rest in peace!
