This was only shown in a petri dish at very high concentrations. You could say the same about a number of chemicals which we also would not survive in that concentration.
I do not understand why people want Ivermectin to work so badly.
It seems to involve a story where they really shame some people for being stupid (the people don't actually have to be stupid, just should be presentable as such with loaded questions, clever editing... what have you) and then while the people are experiencing second hand embarassment for the person, feed them what they need to think to not be ridiculed in mass media like this. This seems to work way too well and it seems they use it ALL THE TIME. Almost every "comedy news show" or opinion piece seems to be formatted like this.
In Brazil, ivermectin working means the president was right. That's why there is such a big effort in Brazil to make it work.
Yeah, look at AZT as an example.
