When the reaction from anti-Sanders people (and I am one) does on to declare that socialism is the USSR it loses the audience Sanders is targeting. To the American youth socialism is not the USSR (regardless of the fact the USSR called itself socialist. The East Germans call themselves Democratic and they were not that either).
This kind of argument by tone deaf Kasparov and his ilk is like shooting blanks. It has no impact on Sanders supporters.
The other socialist that many youths will gravitate to is the new leader of Canada.
If we lose the youth we lose the future - so that is why we need to explain to the youth why Sanders is wrong but in a way that resonates with them.
To address the youth, use humor. See my previous post.
How bout citing the 100 million people killed by socialism/communism in the 20th century. How bout informing them of the German Worker’s Socialist Party and what that brought to the world?
The flaw in your analysis of Kasparov's article is faultier than anything Kasparaov wrote (nothing personal here)
You have the illusion that something Sanders' supporters read, or some logical appeal, will somehow change their minds, and nothing could be further from the truth. There is nothing, and I mean NOTHING that they could read or be "told" that will change their minds.
That is because their adherence to a fundamentally flawed premise (socialism) is emotionally based. They would be impervious to the flaws of socialism or the advantages of capitalism, because they have made up in their minds in advance what they are going to believe.
Kasparov is right, he knows of what he speaks, he grew up and lived through it, and not a single one of the snotty-nosed uber-liberals supporting him has ever done that, except for the ones who HAVE, and they feel that they will be one of the upper party people who will not feel the pain. They will be the ones in charge. Because if they don't view it in that light, and they did live through it, they are brainless cretins. No two ways about it.
There is no reaching those people, except for the grim experience of waiting in line for hours to buy second-rate toilet paper or a fundamental foodstuff, only to find out there isn't enough to go around, that will swing them around. That is the only way they will ever be swayed, and by then, we will be in the throes of it.
Again, nothing personal here so I hope you don't take it personally, but I don't think you understand the mindset of the supporters of Bernie Sanders.
