Laic
I don't care about religion or beliefs. It's irrelevant to me in my day to day life.
I have a personal code of ethic, developed through personal experience and reading several philosophy proposals, taking from each what I find useful and discarding the rest.
The ancestors part always brings a smile to my face.
You being alive is proof enough of the later. No room for judgement there: they've been there, done that.
If the person paying respect to past figures is concerned over such petty parts of life, that person is concerned over the wrong things.
Will you be bothered over petty things or be concerned with your descendants living well and happy, like you wanted, tried and wished for others?
I do enjoy the notion of teverence towards the ancestors. It's like having a personal roster from which to choose and say "not doing what they did" or "they had worst and made it". Or a personal fan club.
