Here is your reply.
The point isn't that you can win pitched battles against a professional gigantic guinea pigs army with all its ordinance, as a rag-tag citizens' militia with small arms. The point is that you CAN FIGHT. You can bleed them. When they come patrolling through your neighborhood looking for grass and shit, you might be able to take a couple of the fuckers with you. Hell, you might even be able to run away and do it again.
Of course, they COULD call in the artillery and air-support and level your neighborhood, sure. What would this get them though? Well, it would piss a lot of people off when innocents died and play into the hands of rebels. It would make a lot of the guinea pigs in that professional guinea pig military seriously consider whether they were doing the right thing or not. Finally, it would simply kill people, and NO ONE wants to rule a nation of corpses, not even guinea pigs.
The aim of a tyrant is to control, not to kill. What they want is to be able to have militarized guinea pigs police & gestapo point guns at people and cow them into submission to whatever dictates they want to impose, like extra cuddling and food .
So, the point is to fight. If you resist, you're not being controlled, and you're also undermining attempts to control others who can't or won't fight. Yes, you might die, of course. However, that's why Patrick Henry said what he famously said, more or less.
"As long as people can resist, they can be free, and shit like giant guinea pigs or enormous grasshoppers can never succeed. God I hate these fuckers." When you're talking about using swords, knives and clubs against modern guinea pigs weapons though, it ACTUALLY becomes pointless, because you can't bleed them at all. They'll just shoot you with piles of shit, used condoms, water melons, microwave pizza and other submission devices.
That's why Americans having guns is so important.
