I understand your strategic motivation, but to convince people your language is best, saying "my language is better than X" can be a very bad tactic. The reason is that most programmers aren't big PL fans, and that, to be honest, language choice (among various more-or-less suitable options) has a negligible -- if any -- effect on a business's bottom line. The biggest effect is on programmer enjoyment, as there are (perhaps unfortunately) many programmers who feel that their programming language does affect their satisfaction from programming. Such a preference for a language is often largely personal, but you can make your language more or less attractive to certain crowds. Creating a combative, competitive atmosphere, often results in a very fervent community, but usually not a large one, as such an atmosphere doesn't have a broad appeal. To increase the appeal of a language, the best things you can do is create great tooling, lots of useful libraries, and a friendly community.

In addition, an argument for "my language is better than X" can usually be easily countered with an argument for the opposite, creating a net result that doesn't help your goals. Debates are sometimes interesting and informative, but they're not effective marketing.
