There is no indication of segregation of the LGBTQ community from others, this is only an example of serving the LGBTQ community, nobody said that the Vespers were limited to LGBTQ and that others could not attend.
And, although your quote by St Paul cannot be disputed, Jesus at the Last Supper spoke, himself, on the need for us to serve others. And indeed the gospel is full of references to serve the marginalized, which in those days were the poor, the orphan, the widow, yet today includes the undocumented immigrant alien, and the LGBTQ.
Employing your logic would call for the end of parish small group ministries including women’s prayer groups, the Knights of Columbus, and multi or bi-lingual Masses.
