You can splashbraw chicken juice all over your kitchen, but you don't have to and it accomplishes nothing. Would you like to continue to splash raw chicken juice all over your kitchen?

100 % that the meat is already tainted so you've got to get it up to temperature anyway.

It's best to keep that mess contained and let the heat kill off all the baddies.

Is dirt and shit on the chicken a realistic problem?

I've never once seen anything on a store-bought chicken that required washing it.

I don’t know. I am aware of this argument and I still wash chicken and pork, and pat dry with a paper towel before cooking. I never wash beef unless it’s packed wet, because I don’t want to ruin the searing. I wash chicken because I find it gross otherwise. I never noticed that this habit of washing caused any problems.

If you take the chicken out of the package and drop it on the floor, the odds probably change to "rinse it without splashing, put it in the cooking container and IMMEDIATELY scrub your hands and the entire sink area, then put the scrubber in the dishwasher and don't use it again until it's been sterilized." But in general the less you handle it the better.

Funny thing, most people who wash chicken wouldn't think of washing a steak.

Side note: one thing people often forget is they touch their spice jars with their chicken/meat/fish hands.
