No, the original comment by <flexie> did not suggest "countries only from Western and Northern Europe". Therefore, your allegations of subtle discrimination are based on your own mistaken reading of the comment:

> ...quite frankly, it would be nice also in Western and Northern Europe to have a supranational investigative body in stead of or in addition to parliamentary hearings, commissions etc. that often require parliament majority which rests with the government parties anyways.<

Alleging discrimination is serious, so you should at least make sure to actually read and think aobut a comment before accusing it's author of being discriminatory.
