When I was starting off in kung fu in the mid 70s, the world was a different place. If there was a weapon brought to a fight, more often than not it was a knife. Now, any moron can go get a gun and pull the trigger. Because of this, martial artists need to be careful with whom they fight and not let over-confidence take them down a path that could, at the very worst, lead to death. Gone are the days when people would just use their fists. Just be careful.
