if I (in particular) wanted to post in my own dialect, where will I post it and where will I discuss it?

In the case of your groups, no problem, there are a lot of English forum where anybody can participate.

Say, if there is a discussion about an Indian topic where only Indians have the expertise or knowledge to participate and wanted to be discussed in their own language, will you deny a non-member to participate in the discussion?

Is QL becoming to politicized that politics now play a great part. So, if you are a Republican, you can not join a discussion with the Democrats in an open forum where what is being discussed is in general and not exclusive?

Precisely the title of my thread, they requested it because they feel they OWN the group and they want exclusivity?
