I think you and them can reach an agreement very easily.

And I will give you the key, the answer.

There are two kinds of socialism.

One is the State's kind. The other is the people's kind.

The people that reject "socialism" don't know it, but they actually reject the State.

Socialism as system, strictly speaking, can be practiced by the people for the people without any danger to anyone, and on a voluntaryist basis.

Isn't that what cooperatives are?

Their enemy is the State. Don't try to convince them to accept the help of the State. They have reasons not to trust it.

Instead, give them socialistic systems raw. In their natural form. Based on free will.
