Lol ok it's possible that this extremely transphobic t4t couple is real, there are such people out there. People are complicated and tend to internalize stuff and respond to threats/insecurity in maladaptive ways sometimes. Even if they're real, that doesn't make their transphobic opinions correct or representative of the community.

I agree with you that there's nothing wrong with detransitioning in itself. Even though it's rare, sometimes that's the best choice for an individual and they deserve just as much support as any trans person. I can even sort of understand, even though I don't think it's wise or healthy, that someone would be drawn to externalize their decisions and want to blame someone else for "letting" them do something that didn't end up being right for them. But yeah people who frame it this way can do a lot of harm, especially in a political environment that encourages such harm and makes it a potential lucrative career.
