Except Jesus Christ who is God in flesh, who other can claim this unity?
Every single person on the planet, that is rather the point.
The interpretation of Christ as the one an only god in flesh, is one that is valid for Christians only, and not for any others. Not that there weren't a whole lot of folks claiming that same title before and since Christ. There is nothing objectively different about Christ than any other religious prophet, and even less so from the perspective of someone who see's all people as "god".
"You're the son of god eh? That's nice, me too. So's my mate Harry. Let's start a club, we'll call ourselves the Children of God"
A Thelemic interpretation would be that Christ is just one example of a man obtaining and actualizing their own god-hood. In terms of long reaching influence a stunning example, but just one none the less, and a part of a certain time and location.
No different to Buddha, for his time and location, Sri Ramakrishna for his time and location, or even Moses for his time and location, nor many others. The language is just a bit different.
Steps in the process of godhood:
1) Obtain spiritual development.
2) Talk to your God, and tell folks what God said i asked to.
3) Hope it takes off.
Being in communication with deity, and realizing your identity as that deity are just stages of development in the qabalistic model. The first you reach tipareth, the second you cross the abyss.

There are examples of magicians that do go off the rails. But it has been my experience that no other system, religion, did not address lust of result in a way that helped me understand how I mess myself up with it, the way Thelema has.
The ones that go off the rails are the ones that hang on to that spiritual power obtained after tipareth, but don't give up their own ego to cross the abyss and recognize their unity/identity with god. Crowley referred to them as "the black brothers"
Reading "I am god" may strike as phenomenal arrogance (I rather think he same when people say Christ is the only way to God, as if all other religions before and since are full of the damned), but in fact you could see it as a humility, in that you give up your personal ego and aspirations and recognise your unity with everything else. In that process being a god doesn't make you better than anyone else, it makes you a part of everyone else.
The real "gods" of Thelema, aren't even gods at all in the traditional sense. They are principles. Nuit, Hadit, Ra-hoor-khuit".
