it's a strawman.
comparing something everybody believes doesn't exist to something some people believe exist and others don't is fallacious.
It's not a strawman in the aspects of the analogy that are being examined: the unfalsifiability of the deity and the following religion. All analogies are made up - so are you claiming that analogies are all strawmen? The only fallacy I can see is if one argues against point X (e.g. the issue of unfalsifiability) by saying that it is not applicable because the concept of the FSM is fabricated...
this would be arguing a strawman, and seems to be what you are doing.
the fact that they're both scientifically unprovable is a detail compared to the absurdity of the FSM's existence.
I disagree. The key here is that they are both unfalsifiable... and if it takes an absurd physical appearance to highlight this issue then so be it... it is not merely "detail compared to the absurdity..." but one of the very issues in question.
more correct would be the celestial teapot, which says there could be, and there might not be, a god out there, without the implicit unlikeliness implied by the FSM.
You have to separate the FSM from Pastafarianism (the religion)... the FSM is no different to the celestial teapot in the issue it raises with regard unfalsifiability. If you can tolerate the teapot, then embrace the FSM.
I admit the religion, Pastafarianism, is entirely different, as it parodies different issues. But the teapot is no different in principle to the FSM.
as a matter of fact, one may even make the analogy less conspicuous , and say god's existence is unprovable just like the existence of a random unmapped celestial rock(asteroid/planet), instead of a teapot(what would a teapot be doing up there?).
Completely different analogy.
Not able to technically prove at the moment is utterly different to being unfalsifiable in the absolute sense.
If we mapped every part of the universe then this "random unmapped celestial rock" would be proven to exist or not exist.
God, and the FSM, are beyond this... they are unfalsifiable.
it's easier to argue god's proof of existence when compared to the flying spaghetti monster as opposed to say, love or souls.
I don't follow? Okay, souls I would consider to be on a par with god in terms of unfalsifiability. But are you suggesting that God is an easier concept to prove if held up against the FSM than against love, or souls?
If so then this in itself is a fallacy... because proof of a concept is nothing to do with comparison but to do with the thing being proven.
Is it easier to believe in God than in the FSM? Possibly, given the parodying nature of the FSM.
But this also isn't anything to do with proof, but rather peoples' ability/willingness to believe.
But if you mean something else, then I do not follow.
