It's deeper than this. If you try to justify why Marijuana is schedule 1, you can't. The only reasonable explanation is "the DEA hates black Americans and poor people and wants to punish them most". That's the reasonable explanation, not the conspiracy.
"The DEA" doesn't have opinions because it's not a person.
Marijuana was made schedule 1 close to 60 years ago, and it's very possible the people who made that decision had racist motivations. It's also possible they didn't and they just wanted to punish anyone who was using marijuana more than other drugs.
"People working at the DEA 60 years after this decision was made are very obviously racist and hate blacks and poor people" is much more of a stretch than "nobody really cares enough about this to change it and it wouldn't change very much anyway," isn't it? Unless, of course, you're not interested in actually understanding why things are the way they are and are more interested in perpetuating some victimhood fantasy.
The decision was undisputably made with racist intentions, and anybody not willing to acknowledge that is not a reliable narrator and isn't worth arguing with. It would be like me trying to argue with someone in a mental institution - it's just not worth it, neither of us will gain anything from it.
I also didn't say everybody at the DEA is racist. You said that, based off of I guess you profiling me as some radical. I'm not, I understand that the DEA is an organization.
But what some people don't acknowledge is there are two types of racism in America: individual racism, and systemic or institional racism. You don't have to say these n-word to be racist. Most of our institutions are structured and designed in such a way to be racist. The DEA is structurally racist, and so is ICE.
It's not some "victimhood fantasy", you're just uneducated on it. But it's real and the rabbit hole goes very deep, I recommend some research on these topics. And, for the record, I'm white, I'm just not blind.
