Social role valorization is a big group of words that means we should treat people in a way that values them for who they are and what they can do. Think of it like this:
Let's say you really like pizza, and you want to order a pizza for lunch with different toppings. You might value the pizza with pepperoni because it's tasty and makes you happy. You might not value the pizza with anchovies because it has a smell you don't like. This is similar to how some people view other people - they might value some people more than others based on things like their appearance, their abilities, or their background.
Social role valorization says that we should try our best not to judge people based on those things. Instead, we should try to see everyone as important and valuable no matter what they look like or what they can do. Just like how every pizza has something special that makes it worth eating, every person has something special that makes them worth knowing and treating well.
When we treat people with kindness and respect, it helps them feel better about themselves and helps them get to do things they want to do. That's why social role valorization is so important - it's about being fair and kind to everyone, just like we would want others to be kind to us.
