Because people choose platforms, not languages.

No, because a language is not (just) a technology, it's a community, and as such, people invest their identities in it. If possible you make an enlightened choice about joining a community that shares your ideas and values and is doing similar kinds of work to you, so they are producing libraries and documentation and hosting relevant and interesting conferences. I often feel that people who lash out at other languages, are people who have come to regret their own choice of community.
