No, I certainly don't know him personally but what I do know is that he participated in gay culture with a very high-profile movie, was a drug addict, and left a child without a father.
Not good fruit. Now, I don't know that he was a bad man, but those are bad things. Certainly not deserving of respect.
And don't think that Ledger necessarily was good because he gave to charity. Almost all Hollywood celebrities give money to charities. That doesn't necessarily make them good because many of those charities have political agendas and are the opposite of good. Can't say about the ones he gave to because don't know what they were but I would not automatically believe them to be healthy ones.
Oh, give me a break. "Gay culture" my foot. Like he's the only actor who's ever played a gay character before? "Brokeback" was just a movie, and people REALLY need to grow up and get over it.
Now, I don't know that he was a bad man, but those are bad things. Certainly not deserving of respect.
He was a human being who never killed anyone or caused any suffering of others, so he deserves prayers and respect in death. It's that simple. You may be petty and immature enough to let superficial things blind you from honoring human life, but I'm not.
You have not listed a single thing that convinces me that it's okay to mock and ridicule him after he's died and his family and friends are left in pain and suffering.
