Afaik, paradox has never made alternate versions for different markets and their approach unfortunately is very one size fits all if recent drama related to CK3 is to be believed. Regardless, a national focus showing "hey, your genocide of an entire group of people is fucking up your country" is hardly a genocide simulator. You're creating a false dilemma. This isn't a black and white issue where showing the reality of an atrocity means someone gets to deliberately revel in joy as they watch a slider showing the number of people in a country slowly tick down. This is clicking the button for a national focus, waiting 70 days of in game time and receiving a national spirit with a myriad of negative effects. It's almost like PDX already did that for a country... oh wait it's literally the exact same thing as the Soviet Union's Great Purge focus. Not exactly attracting hordes of Stalinists. You're justifying your argument with both a false dilemma fallacy and a false equivalency fallacy.
Do we have source the totalist mod is making those dumb focuses a bad thing to do?
The vanilla USSR is awful because it even goes as far as justifying the purge by making a trotskyist coup or white uprising automatic if you fuck it up. It's basically spouting Stalinist points about the necessity of the purge. It's quite the worst example of tastefully implementing leaders taking problematic actions.
