The discussion of what makes good and bad languages has been going on for centuries, and regularly brings up good and interesting points that some might not have heard before. Your post is very broad and mixes different criteria: Popularity, aesthetics, usability, speed etc. You argue that people like different languages; some people irrationally like some and dislike others; not all programmers apply the same evaluation criteria. The problem is - all of these are old arguments, and calls for open-mindedness are nothing new. I'd find it much more interesting if you talked about a technical, concrete example how one can benefit from open-mindedness. E.g.: Decouple your modules so you can use different languages side-by-side; write the same code in two languages so you can battle-test your implementations etc.
