However, I'm not sure banning their party will have the desired effect. Political movements, no matter how evil, can become more appealing, more chic, when their are banned. The fact they can claim they are "persecuted" generates sympathy from people who otherwise would not support them.
No, instead of a ban, a madia campaign reminding the citizenry of the attrocities committed by communists would be more effective. Make it a mandatory part of the school curriculum, as early as the third grade. These sorts of things are more likely to work.
I agree. Banning them won’t solve the problem. A free and open exchange of ideas is essential to any freedom loving people. Even the grotesque and disgusting ideas. Education is the key. Educate the children on the evils of communism as you said. As long as they know and never forget. Hence why memorials and days set aside for memorializing are so important IMO.
How about a novel idea. Hold the communists accountable to their brutal rule. Prosecute and jail them. Remind the useful idiots why they should avoid communism. For some reason, communists get a pass on accountability.
Hunt down the individuals who ran the death camps, the murderers of political prisoners, and put them on trial. Continue the hunt relentlessly for years, exactly like the Israelis did against the Nazis.
