you can't judge a whole nationality based on a couple of encounters and make such assumptions
You're absolutely right. Worth remembering though that this is a discussion where some people have as you say, a couple of encounters, some have 30 years of being from one country and living in the other, some are from one country with their roots and a very large part of their cultural base in the other and yet others who've never been to either and are just throwing their two pennorth in.
The truth, as much as truth exists, is more nuanced.
and i'm disappointed honestly in the adults of this society this is horrible
Even the adults of this society are disappointed with it, however you are right to be angry.
There is a lot of "banter" on here
The Archbishop of Banterbury himself could scarcely do better.
