After another mass shooting, Parkland activists sought momentum. In Texas, the response has been different.

SANTA FE, TEX. — Following a week of quiet introspection after a mass shooting took the lives of 10 people in a high school here, some students are beginning to emerge from a shocked, muted sadness to address what they feel is at the heart of the problem: the nation’s inaction on preventing pervasive gun violence.

They have been treading lightly for fear of upsetting the community at a particularly sensitive moment, in a place where firearms are embedded in the culture, a way of life. They saw the divisiveness that the activism around the Parkland, Fla., school massacre created and the angry public debates it drew in recent months. They are steering clear of discussing gun control, preferring to focus on “gun safety” as a way to show that they don’t want to take guns away from their fellow Texans.

But they are resolute in their belief that some type of change is needed to prevent the killing of more students.
