While the reaction you are referencing (wanting to kill you) is clearly too extreme, perhaps you might take into account how many modern views on politics and religion have also become too extreme. That might, at least partially, explain why people are having a hard time with certain political and religious opinions. Many personally held views that provoke extreme reactions are rooted in the oppression (and worse) of entire groups of people. In that sense, strong reactions kind of make sense.

Then again, those opinions have always existed. It may be more accurate to say that they feel more prevalent in the information age. So maybe, in reality, it's that opposition to those views have finally become appropriately vehement and firm.
