Mate if your that way inclined in the eyes of God everyone is equal. What we do here on earth today is forgotten tomorrow. It does not matter how many people turn out for your funeral its how those that knew you the best remember you.
Keep your emotions in check dude, respect the memory of your grandfather and do not compare him to anyone else on social networks. I doubt he would want to be compared to anyone anyhows. Mate, AFL is not gay, its a great game, Steins did great things in his life and your grandfather most likley did as well.
