Well of course it "sparked debate."
That means the Democrats are against it because they are terrified of guns.

Anyone who’s been near a TV since the Buffalo attack knows Gendron reportedly chose the Top’s Market because it was in an area with a high number of minority residents.
There were other reasons he picked it, however, which he listed under “[s]trategies for success” on page 58.

Among the strategies: “To maximize deaths of the intended target, attack in a high density, highly populated area. … To minimize the chance of instant death from a CCW [carrying a concealed weapon] holder, police, or general armed citizen, body armor and ballistic helmet that will stop the intended threat will be needed.

“Attacking in a weapon-restricted area may decrease the chance of civilian backlash. Schools, courts, or areas where CCW are outlawed or prohibited may be good areas of attack. Areas where CCW permits are low may also fit in this category. Areas with strict gun laws are also great places of attack,” he continued.
