Your are talking about parade, when I'm talking about emotions. Different cultures have different ways to celebrate their deceased, I challenge you to defend the position that any of them have less respect or feel less pain than the other. By the way the word "culture" doesn't only apply to a foreign sub-tribe of Mongolian sheep-herders.

If that's decency, then fuck decency. I am not attached to concept that doesn't add values to humanity and so should you. The kind of decency I subscribe to would start by not pointing fingers at people burying their child. For fuck sake are people so dumb that they need a color to distinguish between fuck heads and genuine pain. Maybe those people feel so much pain that they don't give a fuck about what image they project. What if they don't have enough money to buy black clothes. Either way it's not our fucking business to judge and I would say that it FUCKING DOESN'T MATTER.

You are blind, stop following just because that's that, ask yourself about the essence of reality in order to see the difference between what is tied to reality and what is the result of random by-product of culture which is in itself an evolutionary by-product. I am not diminishing the importance of culture here, I'm simply saying that thinking about it, might prevents us from developing a distorted value system which intrinsically leads to bigger society issues. Grow some critical thinking skills and fucking empathy would you.
