It’s a common talking point in the US that the second amendment was written in a time when the most powerful guns were rifles that shot balls which took tens of seconds, at best, to reload. That the authors of the right to bear arms weren’t thinking about automatic handguns and that the amendment can’t apply to today because of modern weaponry.
Maybe that’s the same for the first amendment too: it was written for a different time, with the technology of the time in mind, and so it can’t apply now.
