I know any response to this is voluntary- but why is it important to you that we all voice an opinion on a freakish and likely unrepeatable event?
Do you believe this is something that could spread if not denounced?
For the record, I have trouble fathoming why anyone would do this- but it appears that you think we're all obligated to denounce it for...the sake of denouncing it?
Why do you not see this as an isolated event that is exceedingly unlikely to be repeated and would cause no broader societal harm if it was?
And why does it matter if we say it's normal or not?
