I read with interest Courtland Milloy's column "Patriotism in the Face of Inequality" {Metro, Jan. 15} and the Jan. 15 editorial "When They Call the Roll for War" decrying the fact that residents of the District of Columbia are being asked to fight in the Persian Gulf while having no voice in Congress, where the vote was taken to sanction the use of arms.

The editorial's point was well made, and it called attention to a serious concern. However, it did not go far enough; for it is not the people of the District alone who live under the onus of partial citizenship, but the residents of all U.S. territories.

Certainly, the people of my district -- the Territory of Guam -- serve as case in point. During the past three wars, the people of Guam have served with distinction in the U.S. armed forces. During the Korean and Vietnam Wars, Guam suffered more casualties per capita than any other U.S. community, and during World War II the territory -- its people all American nationals -- was captured and held for 2 1/2 years by the enemy. The people of Guam have made these sacrifices willingly and with pride despite the fact that they had no voice when the roll call for action was taken in Congress.

I can attest to this because, first by default and later by design and desire, I participated in all three of these wars. It is my fervent hope and wish that I and all of those from Guam who have defended this nation's honor will one day be fully enfranchised. But in all candor, I often fear that my grandson may one day be expressing the same sentiment.

The people of the District at least have the opportunity to vote for the president, giving them some say -- though limited -- about who will make policy on the federal level. This cannot be said for the people of Guam and the other territories.

I do find myself in disagreement with Mr. Milloy's column. In discussing the issue of inequity, he writes, ''Only the most naive among us now doubt that the reason the District does not have a vote in Congress is because the city is predominantly black.''

What Mr. Milloy overlooks and, indeed, what is most ironic about the situation, is the fact that the people of the District, like the people of Guam, are disenfranchised in Congress not because of who they are but because of where they live. In the case of the District, this was a purposeful -- though now an antiquated -- inequity, intended to secure the independence of the federal government. For Guam and the other territories, however, no such rationale exists, and the continued denial of a basic franchise based on place runs counter to the spirit of the Constitution.
