you can't really blame him for using an Alias. This day and age it's dangerous to go without cover.
"Man is least himself when he talks in his own person, Give him a mask and he will speak the truth.", Oscar Wilde.
I use an alias, for that very reason, not because I fear people knowing that I believe thusly. But because with a Government that has already turned it's back to go after a film maker, they have proven if nothing else, that they care nothing for our "Freedom of Speech". This is a dangerous time.
