More to the point, gun legislation is no longer to be weighed against public policy or other rights of other citizens.
Mercifully, perhaps, there were concurring opinions, but this statement pretty much makes it clear that Thomas doesnt think that public policy or other rights are relevant:
When the Second Amendment’s plain text covers an individual’s conduct, the Constitution presumptively protects that conduct. The government must then justify its regulation by demonstrating that it is consistent with the Nation’s historical tradition of firearm regulation. Only then may a court conclude that the individual’s conduct falls outside the Second Amendment’s “unqualified command.” Konigsberg, 366 U. S., at 50, n. 10.ppq
This, imo, is outrageous.
