What's a real-life example of overcoming a barrier that you've seen in your school or community, and what was the outcome?

One real-life example of overcoming a barrier related to social reformism that I've seen in a school or community context is the implementation of inclusive policies and initiatives to support LGBTQ+ students.

In many schools and communities, LGBTQ+ students have historically faced discrimination, bullying, and exclusion, leading to negative mental health outcomes and academic challenges. However, in response to advocacy efforts by students, parents, educators, and community members, many schools and communities have taken steps to address these barriers and promote inclusion and acceptance. Am not supporting to them in other words but they should treated with positivity.
