Did the IRA kill around ten thousands of Brits in one day and kidnapped a few thousands (I'm adjusting to population size here) ? Did the IRA have the sworn objective to eliminate England? Did the IRA join forces with another terrorist organization and a superpower bent on destroying England to encircle England from all directions and join the war?
However, the more important issue is not to get distracted by these sort of things. We can tit-for-tat this endlessly and never get anywhere, and the only way to solve this is to move beyond that. That's what they did in NI.
If we strip away all the violence, forget who did what to who, and all of that, then the inescapable conclusion remains: the IRA was right to protest the treatment of Catholics. Even Ian Paisley later admitted as much. And similarly Hamas is ... right to protest the treatment of Palestinians. That does not mean I condone the violence, like the general rhetoric of Hamas, or anything else. It's just an acknowledgement that 1) at the core of an issue are genuine grievances, and 2) as long as these grievances exist there will always be a Hamas.
You don't need to like these facts to accept it exists. You also don't need to just shrug and do nothing about Hamas. But you DO need to actually solve the rot cause (while you're also fighting Hamas). And for decades Israel has not just flat-out refused to do almost anything, it generally has made things worse. The violence of Israel is not as spectacular as the violence of Hamas, but it absolutely exists.
The reality is much more nuanced and quite frankly contradictory to this simplistic viewpoint. What are Hamas' goals - some kind of peaceful solution or the violent destruction of Israel and expulsion of most Jews from the area? I tend to say the latter. Also, calling what Hamas did on October 7th 'protest' seems weird to me. It committed a massacre and knew damn well it was starting a war.
Going for a less shallow dismissal of your points then:
> Did the IRA kill around ten thousands of Brits in one day and kidnapped a few thousands (I'm adjusting to population size here) ?
The IRA in total killed some 2000 people, representing some 0.2% of the Protestant population of Northern Ireland. Hamas killed in total ~2600 people since 2008 (where I found simple data on Wikipedia), which represents about 0.04% of the population of Israel, taking a very small estimate for the total population. So, in percentages, the IRA was about 5 times as vicious as Hamas (edit: accidentally wrote 50 earlier).
> Did the IRA have the sworn objective to eliminate England?
Yes, the IRA had the objective to eliminate British rule in Northern Ireland entirely, which is quite similar to Hamas's goal of eliminating Israeli rule in all of Israel. I'm not sure if the IRA was as happy to kill any loyalist civilians as Hamas is in killing Israeli civilians, to be fair.
> Did the IRA join forces with another terrorist organization and a superpower bent on destroying England to encircle England from all directions and join the war?
I'm not sure what superpower you refer to here (are you calling Egypt a superpower? Edit - oh, you mean the USSR...). Regardless, Ireland did have some amount of implication in the Troubles, though of course immeasurably less. I'm also not sure why it's more legitimate to bomb civilian buildings or not based on whether those civilians were once supported by outside countries, 50 years ago.
