I'm not sure that "discriminatory" is really a bad thing, particularly in this regard. Am I going to discriminate against an article that I can't read, because it's not in my native language? Definitely! Why wouldn't I? If I can't read it, why would I upvote it or comment on it?

I'd also like to point out hat I actually have tried to read some of the articles written in foreign languages (particularly those that appear to be in Chinese - I'm really interested in learning about what they're talking about over there), but when I put them through Google Translate they're just a garbled mishmash of words due to the imperfect translation technology of today.

The fact of the matter is that articles written in English will be the ones with the most exposure and interaction, simply because most of the users of Steemit are either native English speakers, or have learned English as a second language like yourself. I'm absolutely certain that some articles written in other languages are worth reading - but as most of us just don't have a familiarity with those languages, we simply aren't going to be as active when it comes to upvoting and commenting on them.
