Ignorance is forgiveable willful ignorance not so much.
Words have defined meaning. They do not mean what you want or hope they mean.
To wit Merriam Webster defines Socialism:
Definition of socialism
1
: any of various economic and political theories advocating collective or governmental ownership and administration of the means of production and distribution of goods
2a
: a system of society or group living in which there is no private property
b
: a system or condition of society in which the means of production are owned and controlled by the state
3
: a stage of society in Marxist theory transitional between
capitalism and
communism and distinguished by unequal distribution of goods and pay according to work done
Capitalism and socialism are diametrically opposed. Your sentencee "Socialist countries are simply fair capitalism" is a fine example of an oxymoron. A socialist society by definition must own and control the means of production and distribution of the nation. If you argue government welfare is socialism think again. Government welfare is charity nothing more nothing less. The Nordic nations so many like to point to as examples of socialism are free market capitalists with large welfare expenditures.
