While I agree that sometimes things go too far into the historical and theoretical of what could be rather than dealing with practical issues of now and dealing with them (some of which are connected to some Empires more than older ones), I don't get why it's surprising or something to be wary of that British people would hear far more about the British Empire than other empires, and would have a lot more opinions and emotions about it compared to other empires.
I grew up in the US, we learned fuckall about the British empire after 1812, heard fuckall about it outside brief mentions in the world wars and trade. There were a lot of emotions around American expansionism and American imperialism, but British stuff was discussed academically, if at all. That's generally how things like this work, I would think. In more recent colonies, you probably get more emotions and information. In other countries, the British Empire is a footnote, if that.
It's not that you're especially targetted, it'd that you hear more about yourselves than other people - except when those in power want to hide some shite, then they like to point fingers elsewhere (see anything to do with Civil Rights, British resources can point to the US and other former colonies all damn day then while ignoring the UK's own history. My kids can be taught songs about Rosa Parks, but mentions of British activists and race issues seem to be loudly missing).
Yeah, historical education could be more well-rounded, but there is a limit to what can be taught so we have to prioritize. I would think more would prioritize the British Empire over the Mongol Empire even with the impacts still felt today in parts of Central Asia.
It's wrong to hold the Empire up to modern standards and suggests other Empires are exempt as they were a few hundred years earlier.
People judge and weigh up what they know of the past by both modern legal and ethical standards and personal moral standards. People were doing that even back in the Roman time periods, most of our writing on Sparta are people writing about it centuries after it become a tourist attraction (because they didn't really do much creating themselves). They made a lot of judgements on it but their own standards and whichever tinted view of it (and their own tinted views of their own cultures) they had.
We also judge now with the same thing - there are tons of conversations about how other countries and our own are either horrible or great based on our own legal and ethical standards & personal moral standards.
There might be annoying disagreements about it and it might not always be the best use of time or emotional energy, but I can't see what's 100% wrong about discussing the negatives - then and ramifications now - of the British Empire anymore than any other major historical power and discussing it no more makes others exempt from having done shite than discussing those powers would exempt the British Empire.
People tend to focus on what's relevant or interesting to them. I've written on the impacts of the Mongol, Islamic, and Russian Empires on modern Kazakhstan, but I doubt this would be a major conversation topic for most living in the UK or that most would want to dig into the writings and academic journals on the topic. With the Russian one in living memory, there is a lot more information and obvious ripple effect so people discuss it far more. People push away from it far more (their government is literally trying to push for changing their alphabet to get farther from Russia) than the other ones. It doesn't mean the others aren't very visible, but like with the UK and the Romans, it's just become part of the culture now as an academic talking point, nothing emotional. That's not true in Iran where it's Arabic words and writing that are getting pushed out of the Persian language to the point some who left Iran decade+ ago find it difficult to read writings from there anymore.
From a global perspective, there are a lot of impacts of past empires, but that doesn't mean everyone is going to talk about all of them nor would I think trying to dig into what good they did of much interest. It will fade with time and what hatred there is not isn't terrible effective in doing much anyways, but maybe it can be part of pushing for better trade and enforcement of tax evasion laws throughout the Commonwealth.
