Historically the political debate has been much more overly aggressive. Yet even now I see more overly aggressive 'discussion' than overly 'offended' responses. I don't recognise the culture war between broflakes and snowflakes.Absolutely but the sub question is HOW one exercises that right. Has 21st century society lost the ability to debate without being overly 'offended' or by being overly 'aggressive' (whether by use of hateful words or hateful actions)?
