Those not supporting a backstop and not proposing a realistic alternative support a hard border, even if they will not admit it. For me this comes under the category of DUH! The EU and remainers have basically said you can leave if you wish, but you will not like the consequences because we are going to stick it to the UK so hard you will think you are having an endless litter of kittens. The hard border is just one of the planned methods of messing with the Brexiters.
Of course Ireland is also going to suffer. But the EU can compensate them for losses. Then there was the sad silly bluff by Scotland to terminate their status within the UK and join the EU as an independent land.
There actually is a broad feeling in Ulster that they should leave the UK and unify Ireland once and for all, and lest you think that is just more pie in the sky wishful thinking over nothing it was a condition that was included in the Good Friday Agreement, that they could at their own behest at any time hold a plebiscite on that very issue. Northern Irish have gotten used to an open border since 1998, and they also are widely displeased by their treatment in the UK government.

I would look forward to this as an Irish citizen, but only if it resulted in Ireland eventually leaving the EU itself. I lived there in 2017 and I find being an EU member has really decayed the culture. They were forced in and now should have the guts to leave. They could once again be the Celtic Tiger and in charge of their own destiny rather than submitting to EU cultural imperialism and forced multiculturalism.
