That’s some shouting.
Are Muslims allowed to be gay? Much less the rest of the acronym?
If we asked the same question about Christians the answer would be obvious: there’s a whole range of views, some tolerant and some intolerant. We should recognize the same about Muslims. For example:

That’s why I asked it. The authors of the letter don’t mention anything about gay Muslims in their letter. I’m genuinely curious.
From the letter;
We call upon our community leaders to speak out against this protest and the potential harm it will bring to children both from the 2SLGBTQIA+ and Muslim communities, and the children who identify as being part of both communities.
[Emphasis mine]
Subtle, but it’s there. To be clear, that phrasing leaves open the possibility that they don’t actually accept their claims or identities as legitimate, but the modern use of “identify as” and similar constructs implies at least conditional acceptance of that claim.
