That's why a potent underground racist redneck element can be an important factor in a society. If you don't have that, you open yourself up to outsiders behaving any way they want. Here in Australia, a while back they tried this shit on, some Muslim Men were harassing women on the beach, some Aussie lifeguards got in a fight with them and next thing you know Muslims are rioting. It didn't take long for the rednecks to rally and it was on. The rednecks came out in force and let them know just whose Country they were in.
Same deal here recently, the Muzzies were out their threatening to behead people because of some youtube video, they then threatened to riot, and before you know it, social media was in a frenzy with the rednecks saying 'Just you fucking try it Muzzie scum', Next think you know, the muzzie scumbags backed down and it died a peaceful death. The reason they try this shit on is because they know there will be minimal response. They are typical cowards, the moment they know there will be reasonable opposition, they back down.
