That’s the real answer.
Leftists now, in the past, and throughout all of history don’t give two hoots about building a decent life for themselves. Nor inflicting brutal violence upon others. They just don’t.
We do, so we can’t win. We aren’t willing to be the proverbial ‘loser’, they are and are perfectly find with that. That set of rules always leads the savages to victory, ALWAYS.
The tables can’t turn until we have NO options to live anything close to a life we value. Then we can start to become the savages. That is the cycle of history.
Almost never does the civilized decide to risk it all to put off a threat until it is far too late. We are no exception.
