The MSM was mostly fair and accurate in their reporting. "Horse paste" was mostly a meme or a joke. The NY Times and CNN didn't make jokes about horse paste. The CDC and similar orgs all gave accurate explainers of the use and misuse of Ivermectin (and Hydroxychloroquine).
While a lot of right-wing media like FOX and OAN was absolutely endorsing it. Here's a good one where Tucker Carlson has an Ivermectin booster on his show but apparently conflates it with Hydroxychloroquine.

Not to mention the former president spreading absolute nonsense about HCQ, disinfectant, UV light and whatever else popped up in his twitter feed. This inspired a lot of clapbacks from satirists and unserious opinionators, but you wouldn't see any real news being that sarcastic.
If you had stuck with left-leaning and moderate MSM, traditional news sources during these past few years you would have been very well informed.
