- Do we tag every single Bridget post as transgender, or only Strive posts, or only Strive posts where Bridget is overtly depicted as transgender (with the trans flag, with trans colors, etc)?
The later. Bridget identified as a boy/male in all previous media, and the vast majority of artists keep referring to Bridget as male. Tagging every piece of media as "transgender" would go against the character/creators/artists interests in the same way not tagging Bridget as 1girl in explicitly pro-trans images is, but in this case the "aggression" would be done in a much bigger scale.
Keep tagging all pre-Strive and unspecified imagery of Bridget as 1boy, and limit the use of transgender tags to images that explicitly state it or whose artists wanted to depict Bridget as trans and not as a trap/femboy/otoko no ko.
- What do we call the tag? transgender? transgender (mtf) and transgender (ftm) (is the term "MtF" transphobic)? transgirl and transboy?
Having two tags for trans men and women would cause less headaches in the future. No idea what would be the best name.
- Do we remove the otoko no ko tag if we tag Bridget as transgender? Keep in mind otoko no ko is one of the most searched-for tags on the site.
- Do we replace yaoi with something like transgirl with male? Keep in mind yaoi is one of the most blacklisted tags on the site, and those people won't be happy if this suddenly evades their blacklist.
- What about all the other male-gendered tags used for Bridget? What do we do with things like male pubic hair, male masturbation, topless male, toned male, etc? We either keep using tags like male pubic hair on Bridget even though we're saying she's a transgirl, or we end up with tags like transgirl pubic hair or male-presenting pubic hair, which is just... no.
This is another reason why limiting the change of tags to the few special cases is the better option from a practical standpoint. It reduces the amount of changes that need to be done to tags and filters to a minimum as described by yourself in the other post:
posts under bridget_(guilty_gear) transgender_flag rating:g should be tagged as 1girl. This is a grand total of 11 posts
I know this is a very sensitive topic, but as the owner of Danbooru you should know better than everyone about how important is to have tags that are useful for users, and doing these changes would hinder the searches and filters of a large population for no real benefit.
