Really getting quite frustrated that myself and my friends are ranked as 'trans unfriendly' because we have the audacity to say that trans men experience oppression, while not saying anything negative about any other trans person. This is not a tool for helping you avoid transphobes as advertised. They even don't include slurs used against nonbinary people (such as 'theyfab') in their criteria for being 'trans unfriendly'.

EDIT: Also forgot to mention, there is a lot of intersexism in the guidelines, citing the way that intersex people talk about their oppression - which would help liberate trans people also - as inherently transphobic. I don't like using this term, really, but this is not an add-on for helping you weed out transphobes, it is an app for helping you create a perisex (non-intersex) trans fem only echo chamber.
