These are baseless allegations, impossible generalizations, and repetition of lies. There's a reason the parent contains no factual basis - not one citation - for what it says.

> inferior cultures

This is just ignorant, and against the values you claim to promote. Who are you to say what is ignorant? The ignorance is in the parent comment, which contains knowledge only of vicious stereotypes repeated by others.

> Any individual who embraces western liberal values should be welcome, regardless of where they're from.

A test of "values", however that word is defined (vaguely enough to support whatever the parent wants) and however those particular ones are defined (ditto), has never been a condition. Who are you to outlaw other people's "values"? Must we all share yours, or whichever you approve? I think the parent comment is dangerously anti-Western; should the author be allowed to live in Western countries? (Yes.)
