You can be content with the fact that your position is sound and the people who disagree have no rational grounds for it, and are just assholes.
That's not how the world works. Those people may simply have priorities different from your priorities and could be frustrated that their priorities are given less weight than yours. It doesn't make them wrong in disagreeing with you. How they react to that frustration is what makes them ass holes.
What's more important: the cotton gin or the name Eli Whitney?
What's more important is that you remember the name Eli Whitney. Although you are clearly trying to change the topic by bringing up one of the few times when technology reduced the quality of human condition. Why not mention Norman Borlaug instead? Especially, in the context of this article. Do people think that discovering photo-electric effect was a genius or do they call every genius an "Einstein"?
The fact that their names are already forgotten is not just an injustice to Ciara Judge, Émer Hickey and Sophie Healy-Thow. It is, once again, an attempt to put the political context (their nationality and gender) above the actual achievement. Just try for a second doing the same thing with a headline about a movie actor. As in "... a famous California performer was sentenced to rehab today..." Does it seem like you are telling the full story there? Of course, not.
Science is first and foremost a human endeavor. And any attempt to dehumanize it denigrates it. I have always maintained that every scientist and every mathematician must have it stipulated in writtng that their name appear first in any headline of any article about them if they agree to an interview on which the article is to be based. And if you really don't think people care, then tell me why the names of the actors who play parts in science fiction are known while the names of actual scientists who make discoveries are not known?
Just so you understand, this is only the case in the US. It is very much the result of how the press reports on science. It is not the result of some general trend in human thought about science. It is also fairly new. You yourself mentioned Eli Whitney. Einstein's name is a household item. This is all a result of how scientists were genuinely liked years ago. We went through a cultural period of thinking of scientists as "mad scientists" if they were good at what they did.
And it's not as if science itself was such a boring topic. People will memorize and talk about sports statistics (which are of no consequence) and talk about athletes as if they new them even if they never met them. But the same is not true of science and scientists. Why? Exclusively because of the press. Slashdot editors should know better.
With your bare hands?!?
