Not singling you out in particular but because this is like the nth time I've seen this claim, and it's not true, at least in sentiment PER the actual page the extension comes from
"Shinigami eyes: A browser addon that highlights transphobic and trans-friendly social network pages and users with different colors."
"FAQ: Which criteria is used to determine the label?
This extension is focused on anti-trans (including anti-nonbinary) sentiment, of all flavors: radfem/terf, religious, alt-right etc. (although most of the data is about the first group). See the guidelines below for more details."
Where the addon was always ideologically flawed was in the guidelines portion:
"Not enough to mark as anti-trans: Being a conservative, a SWERF, a bad or mediocre ally, ace-phobic, being concerned with "free speech" and giving voice to "both sides".
While I understand that the addon is transphobia-specific and not "for" other bigotries (ie aphobia), the assumption that SWERF does not correlate to radfeminism (it's in the damn name) when radfem IS a mentioned group to begin with is...a problem.
Further, there IS a general dismissal of some of the targeted harassment of trans men/mascs, and at one point the guidelines equate being called "theyfab" with calling someone a "transmed/truscum" and say such action is simply "mean words that are used to communicate perceived problems within the trans community."
Instead of recognizing that one is not a "mean word" but a movement of valuing medical transition as the most important step in transition and THEN punishing trans people who do not adhere to it, and that the other is a slur targeting typically the same people that transmeds do, the two are held as similar behavior--both of which are discouraged from being marked red.
To be marked green, the addon actually specifically states that being trans is not enough, and being green actually requires advocacy.
It's clear that nonbinary people are an afterthought of the addon while seemingly being included in whose targeting "counts."
Intersex people are also an afterthought, or rather--not thought of at all. The inclusion of "AFAB trans woman" as a transphobic dogwhistle is misguided at best, when there are intersex people who use it in good faith to describe their own experiences.
it's about being a transphobe or trans ally/advocate, not specifically about trans women or even about transmisogyny alone
There are some fucked things that the creator doesn't think is bad enough for a red
There are some fucked things that the creator thinks DOES warrant red
All of the above generally dissuades trans people from being marked green by default and also really desperately tries to keep trans people from being marked red, as the above issues unaware of the intersex or nonbinary impact still assume a cis speaker ("afab trans woman is something cis women say to mock trans people" etc.) (in-fighting language shouldn't mark someone trans red, apparently even with the use of slurs)
The guidelines are clearly not enforced or enforced well because many of the issues I spoke about are explicitly in violation of the terms
Ironically, the addon references multiple multiple times about assuming good-faith and giving benefit of the doubt. It accounts for imperfect allies, misuse of language without malice, "problematic jokes" or "fail(ing) to take a stance." This explicitly-included grace is absent in much of the discourse.
People are not using the guidelines as their metric at all, and while the guidelines irritate me too, the lie that it was made for trans women and that marking trans men is encouraged is gaining a lot more traction and is yet another issue with all of this
