Conservative just means you want things to stay the same or have things to back to how they were when you decided it was good enough to “conserve it”. In this case the fight is about frustration over lack of progress and lack of acknowledgement that police violence and systemic discrimination both very much exist and are actively harming black people. Most of the working world just sees it through a tiny keyhole in that there’s maybe 1 or 2 black software developers in a company of 1000. We need to get better as stewards of society and the companies we work in.
