I have always thought exactly the same thing: It shouldn't be about pretending we are all the same - we are not. It's about accepting that we are different and showing the sort of respect and tolerance that those differences deserve.
Really like the message here. I think it's not always the most helpful thing to say "we are all the same", because, although someone may have good intentions and hope to unify others, acknowledging differences can be important. We cannot wipe away culture and history and things we face. Lately, I've heard a lot of the phrase "we all bleed red", which is great to remind us of our humanity in times of division, but recognizing and addressing differences, how we approach and respect them, is an even further step. We cannot pretend we are all the same as then there is the danger of erasing WHAT makes us who we are.
