Of that, Hermione had little doubt. If the general population in their small village filled with Resistance members and their families learned that one of their greatest enemies was being taught how to use magic effectively without being caught, they would not be pleased. Their secret was jealously guarded. She was sure there was a fear that if the wrong person discovered their methods, it wouldn't take long before the other side learned the best way to combat their magic shields. And if she was honest, they weren't wrong to fear that would happen. She knew better than anyone that that would be exactly what the Dark Lord would order.
