When different groups of people are not guaranteed equal rights, the government can take away the rights of each group one by one, and no one will notice or care until their group is affected. But with equality, the government is forced to take away rights from all people uniformly, which means that any tyranny will be met with stronger pushback since more people are affected. Remember this when you hear people advocate for racial profiling by the government because it is "more efficient". It is one thing to have something like a whites-only immigration policy, but apartheid for your own citizens is a slippery slope that leads to tyranny for everyone. The proof of this is that Israel is always the first country to mandate the latest booster.
