yes. Halloween is apparently a problem. The logical conclusion of this is that all costumes are bad. Which costume can’t be perceived as offensive? With the fitting personal history/experience/background, you can get offended/upset by pretty much everything. Not just costumes, but literarily everything; even in your everyday life. If we get rid of anything that offends anyone, there won’t be anything left. That’s the point where some level of self-reflection should set in: Some things that offend me are really the problem of my own perception.
This kind of out-rage culture is just unknown to me, because I have never encountered anything like that in reality. Fortunately only few people seem to be actually bothered by something, that shouldn’t worry them.
