I'm not judging or anything, but this is typically the mythos of far-right movements. Basically "we are superior to our external adversaries, but the internal enemy prevent us from beating them". This is sightly different, but you should really assess your fears and try to see if this "threat from within" is really that threatening. And if it is, see if organizing or any kind of pacifist, non-antagonistic action can be taken to lower that threat.
