I'm so sorry for your loss - he sounds like he was a great man. It's unfortunate that you're not welcome at the funeral. Is it that you are afraid you'll be treated badly if you go or have you actually been told you're not welcome? In reality, you have a good point that the day is about honouring your uncle, but it's sad that you can't share in that, too. Just remember that funerals are ceremonies for the benefit of those left behind. Knowing this, there's no reason you can't do something on your own to help bring you peace and honour your uncle. You can write a letter to him and burn it, symbolically transforming the words into energy. You can plant a tree or a rose bush. I know it's not the same as being able to say goodbye to his earthly form at the funeral, but whatever you do I believe he will hear it, see it and appreciate it just the same.
