Create a conlang with a few trusted friends. Or learn languages with a few trusted friends. Do not tell others that you know these languages. Analyse target society. Discretely neutralize the worst elements.
Do not run around and yell and scream that the WHOLE target society sucks. Not even on teh interwebs. That is spreading HATE and hate has consequences, as we all know well.
That is how Antifa does it:
1) A group of people learns languages in public education (learning their own languages at home or at specialized schools)
2) Analyses outsider society
3) Discretely neutralizes the worst outsiders (i.e. “fascists”)
Anything else will result in Epic Fail.
Hell is eternal. Only my religion allows euthanasia. Abortion and pornography can only be allowed if euthanasia is allowed as well.
