I know reading context isn't easy for Americans so let me, a foreigner, explain it to you.

That document was written about 10 years after the Americans launched an armed insurrection against their government so they could pay less taxes and due to a grievance about parliamentary representation. In this context when they write about a well regulated Militia being necessary to the security of a "free State," they actually imply that the security guarantee is against a tyrannical state of which they had recently been at war with. They understood that the free state (for white landlords) was precarious and could change so they believed that the hedge against that was local participatory militias. To note here is a "well regulated militia" in this era implies the adoption of military rank and file and internal regulations, not governmental imposed regulations on the existence of the militia or the weaponry itself.

I know reading is very hard. I hope with practice you may someday be able to read and understand context. It takes a lot of effort to become literate. Good luck on your journey.
