Sorry, but you are wrong. Antibiotics are used in the treatment of severe viral infections, because your body is not able to fight secondary infections with bacteria very well. Antibiotics are given to help your body in cases of bad viral infections. Covid-19 is no exception.
https://www.thelancet.com/journals/langlo/article/PIIS2214-1...The point is: there are more mechanisms by which our body can be helped fight covid, and the Ivermectin proponents say that it works only in the early days of the infection, not like a full cure.
There are more ways to fight this disease, you are aware that the virus itself is not what's killing most people, right? Most people die because their body overreacts to the virus and damages the lungs (that is why standard treatment includes steroids to calm down the antibodies). A drug doesn't have to kill off the virus to win.
I have no idea if Ivermectin is helpful or not, but the trashing in the media (even calling it horse dewormer - while it's a human drug as well) before there is any proof against it is just bad, it makes me think there are ulterior motives for this.
