Is it better to use LGBTQIA or MOGII?

I think it differs from person to person, but by far the most common one to use is LGBTQIA+. Most people don't even know what MOGII is, but you could always explain to them if that's what you decide works best for you/the circumstances.

I feel like MOGII is an invitation for people to invite every community into the LGBT+ community. It coincidates with the idea that LGBT+ people are deviants and should be fine with welcoming anyone who is "weird" to society's standards... A good example of that is all the merch found at prides of flags that represent very minor groups, even kinks, when the Lesbian flag is nowhere to be found. While labels can be helpful to people struggling to make sense of their identity / orientation, some are absolutely unecessary if not mocking actual indenties. Some even re-phrase existing identities with no consideration for the peopel who founded the community. In short, I would keep it to LGBT+ since not everyone is comfortable with Queer at all, many intersex people do not associate with the community either, and allies should be comfortable not having a letter dedicated to them if their attachment and allyship is real.

I prefer just LGBT+ before we added all the extra letters. Recognition and acceptance is nice but LGBTQIA is a mouth full and hard for me to remember. Honestly, I don't even know what all the letters in LGBTQIA stand for. In LGBT+ everything is still there because of the plus and it's easy to say and remember what it means. On the other topic, MOGII. I personally have never heard of this one and have no idea what it means or stands for. I can only assume based on the question being asked is that is has to do with the queer community. Again, these are just my personal opinions and I mean no offense to anyone. :)
