I agree that LGBT is less cumbersome, but inclusivity is such an important principle in this space that I think it is prudent to have an acronym which embodies this value. Regarding the “cishet is the norm” idea, I would disagree. Strictly speaking, it is accurate to say that LGBT are in the minority, but personally I’m not married to GSRM. If GSRD (Gender, Sexual and Romantic Diversities) or something is preferable, then I would not complain if that became the prominent shorthand. I just think LGBT is… Flawed. We could do better I think.
