I have no especial love for the Gipper, but some of what you said is opinion rather than fact. For example, under what basis are you calling Iran-Contra treason?
It's because Iran is officially an enemy state. This is on the same level as selling arms to North Korea, ISIS, or Al Qaeda. Feel free to try this. Donate some money to Al Qaeda and see if the government has a problem with it.
Reagan didn't "force" them to share needles any more than he "forced" people to have unprotected sex. Not facilitating legal activity just because it may have secondary adverse impacts to those who engage in the crime is a perfectly moral stance to take.
My point is that he intentionally made the problem worse. It was not an accident. Every medical professional on the planet will tell you that restricting the sale of needles will cause drug users to share needles and spread disease. He knew this, and then he went ahead and did it. Experts basically told him "Americans will die if you do X, Y, and Z." He thought about it for a minute and said "I like the sound of that. Let's make X, Y, and Z the official government policy."
I make a similar claim about Nixon wanting to kill Americans. We had seen what a disaster the war on alcohol was. We had lots of statistics to look at. Alcoholism
increased during prohibition, tax revenue decreased, spending on law enforcement increased, organized crime exploded, petty crime increased. It was a failure in every conceivable way. Nixon knew all of this and said "I want that. Let's do that again. I want more dead Americans. I want more organized crime. I want Mexican drug cartels to have enough money to afford helicopters and military weapons. I want law enforcement spending to skyrocket. I want the prison population to skyrocket." None of this is accidental.
I have no idea if he hated black people or not. The laws you're likely speaking of were in response to the crack epidemic, and if the government had just let the drug spread you would have blamed him for that. It's the typical "heads I win, tails you lose" argument you make whenever policing minority communities comes up - if you aggressively target crime then you're a racist bastard, if you don't then you're "leaving the community to rot."
Saying there was a crack epidemic is extremely misleading and you know it. The 1980s had a cocaine problem. It's true that black communities saw increased cocaine use. You know which other communities saw increased cocaine use? All of them. White people used more cocaine. Hispanic people used more cocaine. Asian people used more cocaine. Aliens from other planets used more cocaine. Cocaine was everywhere. The government specifically targeted drug dealers in black communities by making crack carry much longer prison terms than regular cocaine. If you're selling $100 worth of normal cocaine to white people, you get 5 years in jail. If you're selling $100 worth of crack to black people, you get life in jail. Naturally, drug dealers in white communities tend to be white, and drug dealers in black communities tend to be black. The whole point these lopsided laws was to throw black people in jail. There is absolutely no scientific basis for making cocaine as a salt and cocaine as a base carry different prison terms. None. They have the exact same effects in the brain. They're both extremely addictive. They come from the same plant, sold by the same drug cartel. They have the exact same chemical structure. The only difference is that one has a lower boiling point.
Suppose there was a law saying beer was illegal. Making crack and regular coke have different prison sentences is like giving different prison sentences for selling frozen beer versus selling liquid beer. White people prefer the frozen beer and black people prefer the liquid beer. By sheer coincidence, the one preferred by black people is 10x more illegal. I'm sure racism was not the motivating factor for such a distinction...... even though drug laws and racism historically go hand in hand.
I could just as easily say that about LBJ, who sent tens of thousands of blacks to their deaths in Vietnam on bogus pretenses (Gulf of Tonkin) among other things.
And you would be right. LBJ hated Americans. The people who like LBJ are the same people who watched the Saw movies and concluded Jigsaw was the hero. Draft a man into the army, give him a gun, send him into a war zone, and say "would you like to play a game?"
