Why are people rioting in Ireland ?

Just Loyalists acting up over things not going the way they wanted when it came to Brexit. Along with them losing their rag over Sinn Féin leader Michelle O'Neill attending a funeral during lockdown last year. Though not a word was said Arlene and her DUP twats broke lockdown rules. Not to mention that many Loyalists travelled to Scotland to celebrate Rangers League win. But that's all okay. But if Nationalists do it? Oh they're the devil incarnate. Pff with that type of mentality it's no wonder Britain don't take Northern Ireland seriously. 

The catholic terrorists (Sinn Fein) never have stopped since the 70's.  what we see now is exactly what we saw there in the 80's.  Same catholic terrorists, different decade.  I've been boycotting N.Ireland since the 80's.  People in Eire are cool.

Brexit has made smuggling more difficult for both sides “former” terrorists who now make a nice living from organised crime. So 

they resort to some rabble rousing which isn’t hard to do as the old Catholic v Protestant feelings are always simmering despite the so called peace.

You mean Northern Ireland not Ireland......... the 'excuse' is/final straw  that last year middle of the lockdown  IRA man Bobby Storey died  and Sinn Fien leaders and 5 MLAs ( including  SF Deputy First Minister Michelle O’Neill who dictated the 'stay at home' health messages daily to the public)  organised a huge funeral and street parade  so it is a 'do as I say, not as I do' SF they think they are above the public as far as the law goes....  a public  outcry that the PSNI needed to prosecute them  as they has been doing to members of the public who ignored the 'stay at home' lockdown messages........8-9 months later after NOTHING happened the PSNI/prosecutor is taking no action at all, no fines, no repremand, no nothing.......... and out from under their stone creeped the Unionist paramilitary who are organising, encouraging and supporting idiot teenagers to riot .... and it was the final straw. after Northern Ireland has been sold down the river with Brexit which forces Northern Ireland into no mans land separated from the rest of the UK ...now British citizens are being forced to go through EU customs charges, conditions and paperwork to travel within their own country, they can't visit Britain and take their pet without pet passports and 'rabies' injections when the UK ( or Ireland) don't have rabies, can't move house and take your own furniture without customs paperwork, have to pay importation costs for lots of goods and many goods are banned...no flowers, no plants/trees, fruit/veg and lots of supermarket products, so prices rise IF they are sent and if not there is lack of choice or nothing available

Northern Ireland, not the Republic of Ireland.  It's part of their traditional culture along with cross border smuggling and punishment beatings.  All part of charming local character and a unique, quaint way of life.

Because loyalist drug routes from Britain are under threat because of the NI protocol which includes EU customs checks which the DUP signed up to, now we are lead to believe the south east antrim UDA drug seizures were a "renegade faction" of the UDA

The EU wanted a customs checkpoint between the UK and the EU at all border crossings.  This would have meant a 'hard border' between the Republic of Ireland (an EU member) and Northern Ireland (part of the UK).  That would have breached the Good Friday agreement, so an unworkable compromise was set up - there would be customs checks between Northern Ireland and the ports in Scotland, England and Wales.  This meant an internal border, similar to that which existed between East and West Germany, and this was unnacceptable to the Unionist (mainly Protestant) majority in Northern Ireland.   Within a short space of time, there were warnings coming from groups we hoped had gone quiet for good, warning of the consequences for any personnel staffing or working in any such internal customs set up.   This shut the idea down, as nobody wants to get shot for going to work.   In addition, a noted republican who had been an 'intelligence officer' for the provisional IRA during its terrorist campaign in the 70's and 80's died, and certain members of Sinn Feinn the Republican Party established as a front for that organisation, attended a funeral parade for him.  This was held in breach of the Covid lockdown.   No action was taken by the police service of Northern Ireland to prevent this parade.   The Unionists believed that the Republicans were being given special preference under the law for their activities, and the added grievance grew to the point where the Protestants are now barricading streets and using petrol bombs, the Catholics are responding.
