socialists and communists can peacefully exist in a capitalist system but capitalists can never exist peacefully in a socialist or a communist system.
Socialist and communist have:
*Complete freedom to form party and advocate to make the country socialist
*complete freedom to protest, form unions.
*complete freedom to form worker co operatives, housing co operatives etc.
*complete freedom to write anti capitalist literature and make movies
*if they ever lack money, they can also receive donations and funds from generous people
*complete freedom to call capitalists or anyone that disagrees with them fascists
*complete freedom to live on welfare from the hard earned money of people who paid their taxes
*complete freedom to pool their money (if they have any) to buy land somewhere and start their communes
*complete freedoms to buy a plane ticket and leave the capitalist hellhole and settle in a “true socialist utopia”
*if they find their life hard in a city, they can simply migrate to the other because they live in a vast country.
They have complete freedom and can do anything they like, but capitalists:
*do not have any freedom to start their business
*cannot own a gun
*cannot protest against the system
*cannot own their own property and the house they have can be taken away anytime
*cannot leave the country
*cannot succeed because the state has forced equality on everyone
And so much more
