Like I have said, we've already lost.
Well I hope you have guns. Better lock and load.
More guns than
these loons? Leftists are more heavily armed than they used to be, but that is not a gap that will ever be bridged. These Trump goons don't just own guns, they worship them. Bump Stock, the profane folk god of violence, smiles when they kill.
Sure, these loons have lots of guns. But just because they buy in to the crazy idea that if owning a gun makes you dangerous, owning ten guns makes you ten times as dangerous, and owning a hundred makes you a hundred times as dangerous, there's no need for us to believe such idiocy.
The returns from owning many guns diminish very rapidly. A person with one bolt action hunting rifle with a five round magazine, that is well maintained and that he is highly familiar with, is no less dangerous in a war than a gun fetishist with a dozen assault-style rifles, some with high capacity magazines, bump stocks, or even full auto capability.
Such guns are devastating against schoolchildren, or other crowds of unarmed and untrained (or poorly trained) victims. So they are good for committing war crimes. But not much good for actual warfare.
In a civil war (as in any war) logistics, training, communications, disciplne, and organisation are more important than the number of weapons per combatant.
Having rougly the same number of guns as fighters is ideal for small unit engagements; For wider and larger scale wars, it's also better to have as few different ammunition types as possible, than it is to have a lot of subtly different weapon types available. Having the perfect rifle for a given engagement is not as important as having only one kind of ammunition (and one weapon per soldier) to lug around.
That's why modern armies not only tend to standardize ammunition across weapons systems (so that the same cartridge can be fired by a rifle as is fired by a light machine gun, for example), but also across alliances (so that troops from different NATO nations can share each other's ammunition).
Rugged individualism is good for shooting up a primary school, but to win wars you need disciplined soldiers acting as a unified whole with a shared objective.
The Gravy Seals are a threat to civil order, but not to the integrity of the nation, as long as the authorities and their political masters are ready and willing to stand against them. Without a supportive POTUS, or at the very least the support of a large fraction of the military, they are powerless unless order has temporarily been broken down by a natural disaster.
