resistant

In a physical context, it describes a passive ability to withstand external forces without breaking or degrading. It implies a protective barrier or an inherent toughness that prevents penetration or damage. In a psychological or social context, it carries a sense of stubbornness or reluctance. Unlike "aggressive opposition," being resistant often suggests a defensive posture—a desire to maintain the status quo rather than actively attacking a new idea. Compared to "immune," which implies total protection, "resistant" often suggests a struggle or a degree of effectiveness that may eventually be overcome.
