That is incredibly naive. Just look at history. Fascists were always defeated by violent resistance. And nothing else.
Those who claimed to fight them peacefully all shut up right when they got into power and only quietly showed their discontent behind closed doors, while they kept on living under the fascists. Many even came to support the fascists after it wasn’t so uncouth to do so…
The people who were afraid of doing anything real at first, but certainly opposed fascism with their core, rose up and took arms against them when it became too much. Those were the partisans and their civilian allies in the cities and villages. And thousands and thousands died fighting the fascists alongside the Soviet communists. And that is the only thing that worked.
Commenting on a website will never defeat fascism. If the “holy institutions” of democracy and liberalism failed, how could a silly tiny insignificant postboard succeed?
I wouldn’t call central planning “Marxist”, it’s just better for many things. And Marxism is about trying to find the best solutions scientifically to the issue of capitalism. Namely a revolution and a restructuring of society by the workers “in their image”. And practice of attempting that and building that new society brought new innovations and ideas.
Also, the end goal for Marxists, like for all communists, is and should be a “stateless, moneyless, classless society”. Not in any “words mean different things” way. In a “there is no more class divisions, no more commodity production and capital, and no more state or hierarchical authority. Like anarchists want as well.
