Maybe never.
My teacher told us about gradualism. They will take away our rights so slowly that it would not seem worth dying for and eventually everything is gone.
After the guns are gone I guarantee there will be major changes. population shifts, and genocides. The left are radical murders just waiting for their opportunity to destroy everything of value and everyone who have values. Think Nazi's with no people of worth and capacity to oppose them. This is what we, and our children will face if we do nothing.
