i like nonbinary since they have all the cool pronoun, but they have a pretty bad flag;
transfem and transmasc have cool flags and are cool (says the trans person);
genderfluid has a terrible flag, but someone made an alternative variant that has a butterfly and so many of the gender the term encompasses have really cool flags (also i really like the name genderfae) so its not that big of a downside

i feel like its relevant to mention im ace
