Malvineous:"I myself was not particularly autogynephilic at the beginning"
Timeline doesn't matter. Not everyone has the experience of discovering their "true sexuality", many people genuinely start as one thing, and then change into something else over time, sometimes more than once.
"But purposely gaining weight while being FA may be a kind of fetishistic transvestism."
Maybe for you, but not for others. You're projecting again. FAs who end up finding they have a gainer side say that it happened for any number of different reasons, but trying to become the opposite sex is one I've heard very rarely.
"I don’t know if I ever met a woman as beautiful as the one I see in the mirror"
You're actually just describing autogynephilia.
"I think that fat fetishists have no interest to get laid, even if they first think they have."
Holy shit, so now everyone is secretly asexual too? And then according to you FAs have no desire for a relationship? Literally just look at the personals section, and you'll see that's bullshit. The vast majority of people on earth want to be in an intimate relationship. Stop trying to psychoanalyze people's sexuality and genders, because you're clearly bad at it. If someone says they like a specific thing for a specific reason, maybe just believe them? You don't actually have mind reading powers.
"Living as a fat woman themselves may be the best life for which fat fetishists are made"
Who the hell do you think you are to decide that for them?
"I see no interest to do it since I don’t like sex, even less with men."
You're contradicting yourself. In your first post you wrote:
"It disgusted me at the beginning, but I got used to it.", which indicates you are having sex with men, correct?
"I live what they call 'the carousel'"
You've just contradicted yourself again in the same post. The "cock carousel" refers specifically to women who have a lot of casual hookups instead of wanting long-term relationships.
"For global networks like Fantasyfeeder, I watch the statistics"
Statistics don't dictate people's lives, they're just a record of how often something occurs. Even though it's a sausage party, you can still stand out from the rest and get what you need if you go about it the right way. Also, I wouldn't recommend Fantasy Feeder for dating, apps like Feabie and WooPlus are better.
"it is in fact sexual SM content"
Does everything just look like a secret fetish to you? Mysogyny is prevalent within redpill communities, but I've seen enough of their content to know that they focus mainly on dating strategies, same with passport bros. They speak only vaguely about sexuality, and describe mostly vanilla activities. MGTOW doesn't even do that, their philosophy is to avoid contact with women altogether because they're motivated by fear. Incels of course talk about how sex will never happen. Perhaps a few might be turned on by emotional sadism, but most don't talk the same way as people in fetish communities, they speak with contempt. Even in the link you posted.
"I don't know if there are cis and trans people after the definition of transgender ideology."
Bruh. Of course they exist, people describe how they feel about gender all the time. Stop assuming everyone is lying.
"All adult people can transition if they wish."
Yes they can, and most who do are transgender. There are some people who become convinced that transitioning will be the solution to their mental health problems, only to discover they weren't actually trans in the first place, and now they can't undo the permanent changes to their body. Some have described it as getting a "sexual lobotomy". Detransitioners used to be very rare, but have since grown a lot. The detransitioner subreddit alone has over 50,000 members, and that's not including their other communities and discords. The philosophy you're proposing is literally causing more human misery to exist in the world.
What's particularly troubling about this is that there exists a (thankfully small) number of trans people and chasers online who believe that in every cisgender person, there's a trans person waiting to come out, and that the world would be better if everyone did. They will do and say anything in their power to make that happen through lying and gaslighting, using the very same arguments that OP is making. They call cis people "eggs" and when they're convinced to transition, they've "hatched". This is disturbing and predatory behavior that preys on emotionally vulnerable people who are struggling with their mental health.
I have receipts (CW transphobia):
That video was disturbing as fuck. And enlightening most of the time you hear 4chan and it’s just nazi hitler worship bozos but those people were just like no offense here lonely losers who made a community out of being lonely losers - wild
