I mean, how did that phrase ever catch on after the "not enough indians" part? You ponder that part of the phrase for even just 5 seconds and its pretty obvious. Maybe don't remind your native players about just how tiny a fraction of their peoples are left after what the european settlers first did to them all those years ago?

I mean i don't think its racist really, its kinda more like asking your jewish friend why judaism seems so unpopular compared to the other abrahamic religions, only for them to remind you that it used to be quite a bit more popular until around the 1940s.

Its not so much that its racist, its more that you just look like an ignorant jack ass.
