You’re really trying hard to draw equivalencies between two very different situations.
In the US police kill less than 1,000 per year. Most are white people, many justifiably. So let’s overestimate and say 25% of those are murder. (Clearly not, but work with me). So 250 per year in a country of 350M.
When the Kurds were gassed, a singular event, 3,000-5,000 people were killed. Random people, shelled by the Iraqi military for no reason other than living in the same place as rebellious Kurds. Iraq had a population of 16M at the time.
Those are clearly two VERY different situation you’re trying to draw a parallel between.
Misses the point which is not to justify or downplay either, but that most people lived a very different reality. That doesn't make the brutal mass murder of Kurds any more acceptable. It just underlines that trying to compress the story of those who lived in a given country in any period into just the atrocities is rarely going to be representative of everyone's lives.
However, most Americans don't need to fear for their lives by the police, and most Iraqis aren't Kurds. Most Iraqis weren't gassed or tortured either.
You can't twist the narrative to pretend that the situation of the abused minorities are what the majority of the population experienced. Yes, they were living under their dictator's regime and no they were probably none too happy about the atrocities occurring, but that doesn't mean they didn't have a normal life outside that.
