It is amusing that you like to categorize photos. I shoot down your entire simplistic hypothesis with one simple word;You also didn't include me in your comment in the reply, so I got no notification. Fortunately it's a slow day so I log in here every hour to see what's up. That's like... dirty. Whenever I chop down someones' comment I give an explanation as to why I did it. Usually something like "I agree with everything else but this" or "I chopped your wall of text because it was too big". But that's just me trying to be civil.
You can say that human beings are a race but we're a species. Like canines... canines come in different breeds (subspecies or races).
Race is not a lazy way to do anything. It's just a way to group people because grouping people is what people do.
We group people by profession, by age, by gender, by sex, by whatever. We assign these things because it's easy to quantify them and use them in our day to day lives. There is nothing wrong with grouping people by race. There's nothing dirty in it.
One of the things I work with is databases. I put information into databases and in order for someone to find them easier, I assign useful "tags" to them as it were. It's like when you try and file a group of pictures.
Let me make it simpler for you and everyone to understand.
Say you have pictures on your computer. All the pictures are pictures (all humans are humans) but some pictures are pictures of cats... others are pictures of dogs, some are pictures of wildlife and some are pictures of nature like mountains and rivers... some are pictures of events you've been to and some are pictures of your family and friends at birthdays or weddings.
What is the truly lazy way to deal with all these pictures? The lazy way is to put them all in a single folder named "pictures". That way when you want to find a picture that you're looking for, you'll have a hard time doing it.
What you do is you make a folder for cat pictures, a folder for dog pictures, a folder for all different kinds of pictures and you meticulously organize them. This is the correct way to do it. This is the smart way to do it. The lazy way is to just say they are all pictures and disconsider what kind of pictures they are.
You can choose what kinds of pictures you want in what folder. You can say you want to put dogs and cats together as a "pet folder" and you can group friends and family with event photos. It's your decision on how you group them. But the more meticulous and correct you group them, the easier it is to have access to them. And this is the smart way to do it.
Yours is the lazy and ignorant way.
I could branch out that example in multiple ways but I think you got the point.
EDIT: I'm also not talking about stereotypes, at all... you seem to go full automaton with the replies. Read this and my prev comment carefully. You're the only one who is attacking X set of stereotypes to a race. I'm not even going there.
