I wouldn't call it kindness, but effectiveness. I live in French, I mostly work in English, I also most of the time use English on the Web because I don't want to live in a bubble with a limited set of people. French or not, Turkish or not, Farsi or not, one has to realize it's not always appropriate to stick to their own language, especially on a public forum where the majority of users won't understand it. Anyway, as far as I know, official languages of Canada are English and French, and this is a forum about immigrating to Canada. If a post is for a single user, why not send a private message in whatever language you wish?
