My instinct is to go point by point so DON'T. It always got me in trouble.

Start with the positive.

Then stress that we are listening to all comments. Mass attendance is up and people have been positive (if that's true that people have said anything about the music), but we want to make sure everyone is heard. Emphasize the WHOLE parish and teh WHOLE Church.

Stress that you all study ALL of the Church's teaching, no just Sing to the Lord. Also, the Church hierarchy has indicated some clear preferences and so we are going to follow those.

Don't get into inclusive language, but if you feel you must say that you use it where it is allowed, but not everything can be done that way, paritcularly if you are talking about a Person.

On the social justice thing, I would say that in keeping with the new Missal, the hymns are focused on the worship aspects of the Mass. Any social teaching is to be taught in the homily from that day's reading, and certainly the pastor is open to music that could be included in the leaflet if it is appropriate, etc, etc, but that is a teaching role, not a music role.

Emphasize the organic unity of the Mass and the Tradition. But turn the tables back on them: make it clear that they are a faction (perhaps of ONE) but don't call them that. Emphasize union with the WHOLE Church and how others are happy, etc.

I'm with Liam on hospitality to the musically literate: who here doesn't feel more welcome on vacations when offered a card or booklet?

Still stinging from Noel's barb about "raison d'etres" (where are you, Noel?), who here thinks that "feeling welcomed" while at a vacation Mass due to the presence of a Mass card, which might be juggled among a pulp missal and hymnal in the process, is a necessary rationale for the time and expense while serving the local community? And besides, I know very few people here that use vacation time to go to Mass at Martha's Vineyard; they spend those dollars at colloquium. There I expect Mass cards.

Someone commented on being able to predict what note comes next - I've had extensive training in composition, musicianship, and theory, and a lot of the newer settings go exactly opposite of where I expect them to go! (for example - the "Lamb of God" that starts with a downward major triad, and ENDS with mi - re - mi??) For that reason, I like either having a worship aid or having the numbers up on a board at the front.

Well, color me corrected!
If the publisher whose "worship aides" (arggh) included a Mass ordinary worth singing besides the ICEL, then I'd gladly instruct all our leadership to announce that setting to all "assembled" "congregants" prior to Mass. But oops, that's not the reality in our joint at this time. And as mentioned, we've just managed in the last month to enlist the help of our PIPs to take said "aides" back to bookracks at the end of Masses so as to not have our pews look like a landfill after each Mass. Adding a paper sheet of the settings used, in addition to the "hymnal, missal" and MR3 card, well, just seems excessive at this point. One size never fits all, and YMMV.
Regading hospitality when going to Mass on vacation, W and I just invite ourselves into the choir. Easy. Even did it at Fr. Rutler's Church of the Savior to the early consternation of the organist/choirmaster. But when we sang the Byrd Kyrie (4 voices) by memory, our presence didn't seem to bother him much afterwards.
As I woefully failed to assert, hospitality to visitors can be afforded in many varied ways without having to go to Martha-like extremes making sure everyone's place has a scorecard. But your points are taken.
