I see no opportunity for Red parties to hold on to the Socialism or the Socialist-Red (please, remember Nazi-Socialism). Their next move should be to declare themselves Purple and turn to Centrist politics.
It is the Socialists and Communists who are known to cause genocides. They have been quick to say "common good" without defining the Ethics and living the morality for it! We do have a tax-system (VAT and income tax etc.) that is meant to pay for public services. We have indeed the Democracy to provide the sensitivity for decision-making and I do not see how their insistence on "social justice" is supposed to be so right without the very justice itself. Is then the constant citation of social justice just an excuse for furthering the attack on humanity?
Mao Zedong, Adolf Hitler, Josef Stalin, whether Stalinism or Ukraine "mass death". You should know what I mean, what I imply and that lying publicly is going to be much harder in the time to come! Especially when facing the lawful scrutiny! Reds, be gone!
Ukraine and the genocide by rulers of Soviet Union: https://en.wikipedia.org/wiki/Holodomor.
The Israeli parties have been divided for a while already by blue, blueish and purple colours. Indeed, they have been the first in the World to "abolish" the Red side of politics. Check out: https://en.wikipedia.org/wiki/Politics_of_Israel.
Of the colour red, see also The Masque of the Red Death (The Terror of the Red Mask) and State-terror in France. https://en.wikipedia.org/wiki/The_Masque_of_the_Red_Death by Edgar Allan Poe.
Atheist North Korea seems to be no bragging post either.
Red or not, not really religious people as such, I believe, committing sadism as part of genocide, the genocide of the Armenians by the Ottoman empire: https://en.wikipedia.org/wiki/Armenian_Genocide and https://en.wikipedia.org/wiki/Committee_of_Union_and_Progress. At least there was dictatorship by ideals of Germany and Japan.
Either way, my opinion is here for you to read!
