The three deceptions socialists use:
1. Repressive Tolerance
2. Pressure from Above - Pressure From Below
3. The Four Stages of Subversion
Four Stages of Subversion
Look for the switch between stages: For instance, in the 60's leftist professors would say "question authority". Now in 2020 leftist profs allow no dissent. That's because "question authority" (in the 1960s) was part of the destabilization stage since leftists were not in control of education at that time. Now screaming "racist! sexist! fascist!" - whatever they use to shut you up - is part of normalization stage since the leftists now control the universities.
The article below contains a great video explanation of all four stages.
