These remembrance days are largely meaningless. This is essentially political clickbait to get everyone riled up on both sides.

Each Congress, Representatives and Senators typically introduce hundreds of measures to recognize, support, honor, or acknowledge individuals, groups, and events with a national day, week, or month.
… By recognizing and memorializing important historical figures, groups, and events, date-specific commemorative measures can be used to help establish collective memory and for Members to connect with constituents and fulfill representational responsibilities.

I added italics, because this does seem like a good way to connect with constituents one way or another.
