No, because then it isn't remotely the same example. It's not a slight change in the analogy, in this new case the person has to go out of their way to step on your toes, so they are clearly intending to do it. You might not be able to prove intent, but you can clearly infer it from the fact they deliberately walked over to you to step on your toes.
How about this it's a busy street, people occasionally step on each others toes.
- Some people walk in towards their destination, and step on others toes occasionally and equally, if they happen to step on someone's toes it is an accident, but perhaps one that could have been avoided if they were extra careful, however if they do step on someone's toes they are genuinely sorry.
- Some people are extra cautious and constantly avoid stepping on peoples toes, they still however do it occasionally it is unavoidable, but it takes them twice as long to get anywhere.
- Other actively look to step on peoples toes (but only if they have blonde hair), they are generally sly about it and make it look like an accident.
You have blonde hair, and notice your toes get stepped on more often than your brunette friend's.
Here walker one could become more like walker two. However there is a drawback, so it might not be that easy to change that behaviour, they don't mean to hurt people it is just a consequence of getting from A to B. Walker three is unlikely to change his behaviour, he enjoys the pain he inflicts.
I think that reflects the fact you can't detect the intent, that someone can still get hurt despite your best efforts and also that someone is targeted more than others due to no fault of their own.
You are saying more people should try to be like walker two (which I agree is a noble goal). I'm saying even if everyone was like walker two, you would still get hurt, it is a good idea to get some steel toe caps, but also when you get your toe trod on it is better to think of the person as walker one or two than three (until they prove otherwise) for your own mental health.
