Why would they? They know they have the nearly 30% support it takes to overwhelm a society and, crucially, they know roughly 30% are complacent enough to allow their takeover and whatever atrocities they think are required to ‘fix’ society.
Remember that when fascism threatened to overwhelm us in the 1930s, only about 30% of society were onboard with it; 30% were actively against it, and roughly 30% were in denial, didn’t want to talk about it, or were just hoping it would go away somehow if they just ignored it.
