And on top of that, even in cases where it is demonstrably true that any given group/population/region, say, does more crime than the average, it almost always boils down to the fault being laid on the existing discrimination against that group causing further harm.
Like how racists will say that black people do more crime because they're fatherless, (and that it's a result of their culture that causes the fatherlessness) but don't see the problem with specifically over-policing those neighborhoods and arresting the fathers they say need to be there for the kids, thus perpetuating the cycle in the first place.
Even if it were true that, somehow, miraculously, trans people did indeed do more crime than the average for their gender or sex, they also face multiple times higher abuse rates than non-trans people, which is known to perpetuate cyclical violence. But yet, somehow, they still do the same amount of crime as everyone else (at least, comparative to their birth sex, generally.)
I prefer using the self checkout, I don't consider it work, because I also consider it work to mentally deal with meaningless small talk, and to deal with waiting in line for ten minutes when I'm buying just a few items.
You might feel like it's work for you, and that's fine. You can then use the staffed checkout lanes, which are explicitly there for anyone who dislikes doing self checkout.
The problem isn't doing "work" by using self checkouts, the problem is capitalist cost-cutting, which would be done with or without self checkout machines.
