...only to be couped by those same hardliners who went through a succession of like-minded Lord Protectors up until 1848 of all years. Predictably, they redialed back the persecution of the Irish and even turned it up to 12. In fact, I'll go further and say that I'm still surprised that Ireland even has a nationalist party to begin with, since the island is now heavily English Protestant.
And after the Commonwealth retained control of New England, they invaded New France (or rather New Britain and Oliveria*) and expelled the entire French Catholic population (slaughtering anyone who remained and/or refused to convert; and yes, those Grandees and the Lord Protectors that succeeded them were the Jaysh ad-Din¹ of their heyday). The fact that Louisiana and Texas, in addition to being the main centers of French culture in North America, are one of the most loyal to the Stuart Emperors of Maryland is a testament to their treatment under the Commonwealth.

And by the way
@piratedude, before you start saying that the atrocities weren't that bad, consider that Ireland lost some 75% of their pre-Commonwealth population (with the potato famine, which occurred in the final days of the Dominate claiming another 10%) while Oliveria and New Britain are entirely anglophone, with small percentages of First Nation and immigrants speaking their own languages.* Then consider the fact that many Louisianais consider the 24th of June (the Commonwealth invasion happened on St. John the Baptist Day of all days) as a day of mourning over their lost homeland.
*mostly from other parts of the world where the Commonwealth colonized (ie India and Subsaharan Africa), as well as other Protestant nations (which New England upon independence prioritized migration from)
There's a lot to unpack here, but simply put thats a lot of exaggeration (and some outright lies) that only makes sense if you're squinting at it.
To start, while the position of Lord Protector was abolished in the aftermath of of the Great Chartist Strike of '48 in favor of the popularly elected tri-consulate (among other reforms), the last real military grandee to hold the position was in 1803, and though some would remain in the council of state for a few decades it was a shell of itself.
And neither was the Commonwealth as uniformly and rabidly anti-catholic as you so desperately want to paint them to fit your narrative. There were three distinct periods of anti-catholicism; the first round came after the last Stuart attempt at restoration by "king" James via Ireland, which was the harshest in terms of people directly killed by the State and saw catholics explicitly excluded from the laws protecting religious freedom;
the second was after they had wrestled control of New France. Yes, lots of catholics fled or were expelled, but only a few were actually killed in that period, you can't just take the casualties from the actual battles fought with france to obtain the land and say that thats bloody French-catholic repression;
And the third, after Great '48, was less anti-catholic and more anti-nationalist given that full religious freedom was one of the reforms that was pushed through, it just happened that the majority of the nationalists that tried to use the opportunity to break away from the commonwealth were catholics.
And i hate whataboutism, but i cant help that point out that the stuart descended Emperors of Columbia did their fair share to whipe out native culture as well as being the last ones in the new world to abolish slavery.
I don't know what propaganda reel you got your stats from for the depopulation of Ireland from but they're almost hilariously wrong. The two biggest cities in ireland may have lost 3/4ths of their population but certainly not the whole damn island. On average the population grew in ireland for most if the time, though you are right that the mismanagement of the potato famine killed 10% and drove another 15% to immigrate.
And "heavily english protestant" is debatable just because a few chunks are solidly protestant doesn't mean most of Ireland is protestant, and the INP specifically ignores religious differences allowing them wider appeal than their more sectarian rivals
