It is in human nature that most people prefer not to be demonised by their abhorrent character/morals. One way to ‘break free’ or cover them up, is to demonise another minority. Of course, there is a lot of examples from extreme to light.
In context with your post, that minority does seem to be the most ostracised within the majority (even the non-offending) - to the situation that harassment and ‘murder?’ By most communities is tolerated.
The situation can be observed everywhere, online and offline; and one point can be ruled out in some cases “murder is justified if the person was a pedophile (non-offending & offending)”.
This is one of the most extreme cases of improving your character at the cost of others. Harassment will remain harassment no matter what.
Not suprising. With all those trends and temporary fads, all those clothes have to go somewhere.
