But them trying to stop you didn't stop your determination, did it? Because if it did, then it was you that ended it, because you let your determination die.
If you are in a car, driving, and come up against a roadblock, does it stop you from driving? No..you have to keep driving anyway - either through the roadblock or around it, or somehow redirect. But, you don't park the car and say, I guess I'm done driving.
