You've been looking in the wrong direction, the dangers are coming from the right.

". And yet we are hearing about it on a forum in Ireland as if neo Nazis are swarming on the streets and attacking Jewish people."

They are; not in Ireland, but all-time levels in the USA. Remember the Charlottesville march?

Because discussion should be informed. "Just Asking Questions" is trolling. Not bothering to do a minimum of investigation prior to bringing up a point of discussion, is essentially trolling.

"These racist thugs must be thrown out"

Sadly, they're likely to be US citizens and probably won't have any consequences for their hate speech - the 1st Amendment to the Constitution protects them

But, what would you do to prevent this behavior in the future? We can, of course, discuss. A hate speech/incitement law would be a good start in the US but difficult to pass as it's subjective and there's a long history of free speech. It's one of the places Ireland falls down in my view, there's no freedom of speech here to the level the US has it. Holdover from English law.

However, no reason these goons can't be doxxed and all their employers know about them. My guess is it's likely that's happening. SPLC and the ADL learning who they are would be a plus as well.

Or more Northerly areas can grow fruit and berries where they couldn't before.

That 8 million would be the whole island I believe. Currently just over 7, so not a million miles away...

This actually shows we're nowhere near "merely keeping us from having a falling population" - in fact we seem to be in the middle of one of the highest population increase in the recent history. And the fact the growth is so net immigration based means in the next few years we will see a lot more births than normally expected with a natural population increase, putting further pressure on already too far streched systems.

Anecdotally the rents are unaffordable for a significant percent of the population, getting a place in a school and a GP practice is much more difficult and the hospital overcrowding and A&E waiting times are insane. And yes all those things you mentioned are also true, Ireland makes a lot of money, but also people need houses, schools and hospitals which take time to be build. No one said we should make the things even worse like the UK did, but a little more responsibility is needed.

And this is not even a right wing thing, proper right wing will be in the interest of landlords and business to have even more people, not less.

Sees like some of the nuts in PBP have been reading this thread and believe that an armed coup is possible if a left-wing government takes over.

That being said, as it appears their left-wing government won't include any of FF, FG, Greens, SF and Labour, it is not likely to ever happen, so the imagined threat isn't possible either.
