Ffs, someone is trying to learn a bit more about the complexities of NI and this is the response they get?
I’m from NI, still live here, and don’t understand the ins and outs of every different faction, or the full and complicated history of the troubles from both sides. Give the OP a break ffs.
In answer to your question OP- on the face of it, it’s to do with the Protestant/Unionist/Loyalist community being pissed off about the sea border between undermining the union.
In reality, the it’s now harder to get drugs in through the ports in the north, and that’s pissing off the Loyalist Paramilitaries because £££. In turn, they’ve stoked up young people in their communities to “protest” against the sea border, claiming that it’s an act of patriotism for their country, without dirtying their hands.
It’s fucked up and frankly embarrassing as a Protestant/ Unionist that these people are trying to drag us back despite what we’ve come through as a community in the last 20 years.
