You pretty much completely negated whatever point you had, so I'm not sure what your point is now. Every drug has positive and negative side effects. Just because a small percentage of people have adverse side effects doesn't mean that the drug is unsafe, otherwise ALL DRUGS are unsafe by this definition. So if your point is that all drugs, including hydroxychloroquine, are unsafe, then fine, you are correct by this absurd definition.
However, to more reasonable people, hydroxychloroquine is safe because the vast majority of people can take it daily for decades without any adverse effects. People with lupus and rheumatoid arthritis take it daily, with most having no adverse effects. It's provably more safe than a drug like Acetominophen. Are there people who suffer adverse effects by taking it? Yes. But it's a small minority of people. And if the only definition of "safe" is that no one ever gets adverse effects, then there is no such chemical that qualifies to be safe, including water. Water in large enough doses will kill people.
The reason why I'm saying it's politicized is because the very mention of the drug has become politicized. Look at your reaction and other responses. I never mentioned COVID-19, and you were the one to bring it up. The drug has been caught up in the nonsense with COVID-19 and Trump taking it, but that was never the point. I never mentioned that, all I did was talk about whether or not it's safe, which it is. People like you who know nothing about the drug start echoing talking points from the news because you think you're so much smarter than other people, and yet you don't even read basic information about the drug. If you did, you would speak more educatedly about the drug instead of parrot what you heard on Twitter.
If you don't believe what was written by the CDC and the FDA, then that's your right to believe whatever it is that you want. But it's not science, it's religion. You want to believe that hydroxychloroquine is a dangerous drug even against science. Even the research paper that you linked to has been resoundly criticized with science and math. But I guess since you religiously believe what you want to believe, you'll stick with believing that the paper is correct instead of following the science.
