Or do we want them to stand out?

Because fitting in is to fit in our way of thinking, our way of solving problems. Fitting in is to make our lives easier because we have designed the system and it is a pain to work with outliers.

If they stand out, we need to cater to their needs. We need to adjust our system to accommodate. And, sometimes we are not willing to do that. We need to tweak the rules of our carefully crafted assembly line of processes that industrialization has taught us. 

It is good to desire excellence and innovation. It is good to desire uniqueness and perspectives. It is. Desiring is one thing. Accepting and rolling with it is another.
