Dunno which 'they' the title is referring to, but from what I have seen on tv, the Q word is openly accepted by homosexuals--among themselves anyway. Not that I watch much TV anymore. From the internets urban dictionary:
LGBTQ: "LGBTQ" is an acronym that originated in the 1990s and replaced what was formerly known as "the gay community." The acronymn was created to be more inclusive of diverse groups. LGBTQ stands for lesbian, gay, bisexual, transgender, and queer (and/or questioning) individuals/identities.
No, I do not know what the difference is between the q designation and the gay designation.
