Are we wimps and cowards or are we just deluded about our corruption?

We tolerate a corrupt slandering media and schools that brainwash our children in cultural Marxism and general decadence, perhaps because they do it nonviolently, but why do we still tolerate violent gangs like the Crips and Bloods, why are there Mexican gangs and drug lords in the U.S., why is there still a Mafia in the U.S? And why do we tolerate wide open borders for illegal immigrants and other criminals?

How can we defend democracy if its freedom leads to people who destroy us? The police could make these people disappear if we wanted them to, and if the police weren't enough the army could finish the job, and it could be done legally, democratically, without becoming fascists on the right or the left. So why don't we do it? What or who is stopping us? Are we colossal wimps and cowards or are we just deluded about our own corruption?
