Initially some used “#imoga” over “#mogai” because the mogai tag was full of discourse and antagonism, some still do. I primarily used it because it sounded more harmonious transcribing when speaking.

Some see that IMOGA emphasize intersex inclusion, also because some exclusionists, and others that are unaware/know little about mogai, use “…gender and identities” instead of “…gender alignments, and intersex”. And that intersex is inherently marginalized, it could be redundant to say “marginalized orientations, gender alignments, and intersex” (because in this case, some put the serial comma immediately after orientations). 

However, I believe the best transcriptions of MOGAI would be: marginalized orientations and gender alignments and intersex; marginalized orientations and gender alignments, and intersex. Notice how the conjunctions (“and”) in “…orientations and gender…, and intersex” make a difference now that you know the issues. I see that the serial/Oxford comma after “orientations” could also mean that it’s any gender alignment, not just the marginalized ones, and the lack of conjunction before “gender alignments” would mean that “gender alignments and intersex” are the “marginalized orientations” (specifically in “marginalized orientations, gender alignments and intersex”).
