What happened after Project Mayhem?

"Marla and Tyler look alike"
This is a reach, yes neither of them really gives a *beep* about appearance, but to say they dress alike, would need much more telling evidence than what's provided, and their hairstyles are not alike, Tyler has short and spiked hair until the end when he has a buzz cut, whereas Marla has a tangled ratty mess because she can't afford to get it styled.
"Marla and the narrator look alike"
Other than the one screenshot he gives this is completely false, he is seen wearing button downs in almost every scene.
"Marla has no reflection"
I almost laughed out loud when I read this, how can a self proclaimed fight club expert just forget about the fact that the entire breast examination scene is shot in a mirror showing Marla's face, neck, and shoulders.
"Marla takes over jack in the thrift store"
This point relies heavily on the assumption that Marla is selling the narrators jeans, which they aren't. The website says "What are the odds that two dryers right next to each other would contain only men?s blue jeans" which is a question based on the false premise that the only things in the dryers were jeans, they weren't, the narrator even says as she leaves "you left half your clothes" meaning that there are more clothes like shirts in the dryers and she went for the jeans because they were the most valuable. So a more relevant question would be if these are the narrators clothes then why would he combine shirts and jeans in both dryers he used rather than putting all his jeans in one and everything else in the other? And the answer is he didn't, those dryers were each owned by different people and half of each of those people's clothes were jeans that Marla stole.
I can't refute the next two points because the part on the plane is true but does nothing to prove Marla is fake, and there is a theme of masculinity throughout the movie, however the point the movie is trying to make is that society is taking away people's masculinity, not that Marla is.
"Big rubbery one"
1.if you have to change the coloration of the scene for what Marla is holding to resemble a dildo, then in all likelihood it was either a joke/Easter egg left for eagle-eye viewers or it was something completely innocent that looks like a dildo if the scene's colors are messed up.
2.how the hell is owning a dildo symbolic of surrendering his masculinity to testicular cancer? That makes no sense, he's probably not gonna use it unless you think he's putting it up his ass, and it wouldn't make sense as a metaphor for woman needing it instead of him post-testicular cancer, because most testicular cancer victims still have a dick and can still have sex with maybe less sex drive, they just can't produce sperm, just like people who have vasectomies.
3. Big rubbery one is an expression, not a common one, but I've definitely heard it before.
4.no matter how hard this guy reaches there is only one explanation that makes sense for the "that's not a threat to you" line and that is to say she prefers sex with men to dildos. It would not make sense at all the way he claims, because if he was turning into Marla it would still be a threat because he could put it in his ass.
"The vibrating suitcase"
It's hard to give much evidence as to why this can't be a hint, but I think the evidence given in favor of it is flimsy, which is really bad for his argument because this is the strongest piece of evidence he provides. And throwers is the most common term for baggage handlers not a sexual reference.
I would go on but it's three AM and I think I've proved my point that the jack durden THEORY relies on false assumptions, and flimsy evidence to prove a point that, if it were true, would take away from the very important message the movie holds about our society.
Also, what are the odds no one would realize this until 15 years later if it were actually true.
