People should travel (and live!) more abroad for a while. As you wrote, many seem to be surprised that the people living in Asia, Africa, etc. are humans too (in the sense of: people with history, dreams, expectations on life, etc.)

My hope is that the Internet will have the positive effect of removing this misperception in the long run.

Personally, my eyes were opened quite a while ago when the US dropped one of the largest conventional bombs on some mountain region in Afghanistan where they suspected Taliban leaders to hide out. The next day some guy on Reddit wrote (loosely paraphrased) "Hey, that's were I always travel with my motorbike! Glad I wasn't there when that bomb went down..." and posted a picture of where the bomb hit, with his motorbike in the foreground.

The British oppressed the Irish for 800 years with a systematic destruction of culture and contribution to genocide which halved the population and then recently had the audacity to assume Ireland would be allies during Brexit negotiations.

The negotiations and the deal were extremely dumb in many ways (as is Brexit overall), but this is a really weird take on it. It does make sense that Britain would try to use the fact that Ireland has a substantial amount of trade with the UK and it is not inconceivable that Ireland might therefore in its own self-interest want some sort of deal.

Weird or not, that's the take in many places, Ireland and Afghanistan alike. A modest proposal, eh?

You're mistaken if you think that even the more recent atrocities like the great famine or the violent oppression of the Irish home rule (and ultimately independence) movement have informed the Irish response to Brexit negotiations. It is to their credit that they're pragmatic people, since they could easily dish out a black-eye to the UK if they wanted to.

If Éire had a few UK sponsored drone bombings I’d bet that would change real quick. Otherwise I take your point.

We have a PM who is filmed responding to a protester in front of dozens of press and TV cameras at an event with "there's no press here", while hearing constant shutter clicks audible in the background. That he's completely tone deaf dealing with the EU, our neighbours or electorate shouldn't be the least bit surprising.

That said, since Irish independence there has been a good degree of desired closeness between the two countries, not least the passport free freedom of movement and voting, which survived the worst of the NI violence. Looking back that can seem surprising. Record numbers of Brits have been applying for Irish passports (a remarkably high number are eligible) since the Brexit vote.
