Can you please clarify what part of being sexual orientation involves wanting the world to treat you as something that you are materially not?
You posted this: ”To elaborate, there often seems to be the insinuation that trans people are in some way mentally ill - how many times have we heard the argument "well, we don't affirm the beliefs of anorexic people that think they're fat."”
”However, both gay and trans are orientations driven by feelings rather than scientific proof. It took decades before gay people were accepted and they were at times seen as indecent and sent for conversion therapy.”
But you really seem to be missing the significant difference. That people who are same sex attracted do not demand any additional accommodations be made for them. They rightfully expect to be treated equally for who they are. Nothing more and it doesn’t require anyone to believe that this group are something that they are materially not. Whether you choose to try to draw those comparisons about ‘feelings’ and whether they are provable or not. A person who is same sex attracted has an arousal response to people of the same sex as them. Not the other sex. Or else they would be bisexual.
Either way, there is something material to their body’s responses. And again, they don’t demand additional accommodations by society.
A male person who expects society to treat him as a female person is demanding additional accommodation from others. It means other people have to accommodate that person’s belief which is based purely on philosophical belief. And yes, post modernist theory that someone is what they say they are. But they are not a female person in any way. And reducing people to ‘butch lesbians’ etc is just someone labelling others who don’t conform to sex based stereotypes. It is a very weak point to bring in. A male ‘presenting’ as a female person still does not change material reality that they are male.
Not only are they still male, they are also only performing their own concept, as a male person, of what they believe a female life experience is. They can never be what they want to be, because that is the material reality of their situation. Every single interaction that person experiences, is one of a male person presenting as a female person.
The same is most certainly not true of a ‘butch lesbian’. Because they are a female person who merely presents a different version of being female while still being female. Ie. They are always a female person and they know this and don’t expect the world to treat them as ‘male’.
The additional accommodation includes laws and policies allowing those male people to be treated as a female person. One aspect of this can be explained that these male people not only have access spaces for male people, they want the extra right of access to female single sex space. What other group of people expect this additional right? Another aspect is that those male people have not experienced the negative sexist discrimination that female people have and still do experience from birth, yet also want to access opportunities set aside for those female people to overcome that negative sexist discrimination that they have experienced. I am not saying that those male people don’t experience their own unique issues, but they should not be removing opportunities set up for female people in this way. Again, another additional accommodation, and what other group is making these demands?
So, same sex attracted people live according to their material reality. It is one where there is a bodily response. No one same sex attracted is demanding someone treat them as being different from
what they materially are. Plus, if someone treated the person who was same sex attracted as them being heterosexual, it doesn’t disprove that they are same sex attracted. If it wasn’t discriminatory or abusive, would it even matter to that same sex attracted person?
On the other hand, a group of people do demand that people treat them as if they were something they materially are not. They claim their gender identity makes them something they are materially not. This would be fine if they didn’t demand others comply with this philosophical belief. But they do demand compliance.
How is being ‘trans’ an orientation exactly? That usage sounds more like forced teaming.
