I think that coming from afar to comment at a meeting for community member input would be odd, however coming to comment at the upcoming City Council and Planning Commission joint study session would be fine.
The message from a nonresident member of a regional group would be something along these lines: that housing affordability is a regional crisis; increasing supply to match demand is an essential to improving the situation; there is a growing number of supporters around the region, and hopefully MP will join other cities in contributing to solutions.
Facts will be welcome, and will add helpful perspective. The most excellent cartoons of monsters, and messaging characterizing those with opposing points of view as selfish NIMBIES will not be welcome or helpful to the cause in the MP venue.
