I assume you live in the US. If TSHTF in an urban environment, are more guns going to help?

If you don't want to be under the thumb of anyone who else who is either armed, or physically stronger, or outnumbers you; then yes - they are required.

I would say the world needs less guns, not more. Be the change.

The only thing that holds civilization together is violence / men willing to die to enforce the structure they believe in. Without it the biggest guy in the room was is able to do what he wants. After all, anyone who doesn't like it can be summarily beat to death. Local leaders might have more armed men, that would come kill him for this action later / maybe not. Guns are a force equalizer that allow a 110 lb 5'2" woman to tell a 6'9" 220 lb man no.

Can you see how this runs counter to the rest of the advice. i.e. get friendly with the neighbours, plant seeds but arm yourself just in case?...

Your neighbors need to be armed too. Ideally you can work out a mutual defense plan with them. When an angry anti-White mob shows up, ready to rape/murder/destroy, you don't want to be dependent upon out-numbering them.

Let's hope you're wrong on this!

Look at the history of Haiti, and more recently Rhodesia and South Africa. I'm not.
