Bulgaria: No need to sign anything, it’s already done. Everyone has the equal right to marry the opposite sex, and nobody can change (de facto) their legal gender. Everyone is already accepting of the LGBT people, as long as they don’t show it publicly.

Jokes aside, outside of Sofia the public opinion is that there are matters much more important than that. Homophobia is also widespread so it’s a political suicide to ratify something like this. The Istanbul convention was a huge “scandal” for just mentioning that it applies to trans women as well. There was a huge disinformation campaign and it worked. We ratified it anyways because it was integrated into an EU directive so yay?
