I’ve invited her to edit her first post to make that clarification and yet she refuses. Seems curious. One would think she was being intentionally deceitful.
Well, it seems that there was clarification made. Even if there wasn't, I'm not even sure why it's such an important point to clarify in the first place. It seemed clear enough to me that the underlying point was that the US has a long history of immigration and most of its present-day population descended from immigrants to this continent.
That is a historical fact, and the percentage cited was based on US government statistics regarding the percentage of Native Americans (2%, which would mean that 98% are not Native Americans). That seemed fair enough and clear enough, although I myself might question those statistics, as it's possible it may be undercounted, depending on how much Native American ancestry is required - or if it requires actual tribal membership to be counted. But I wouldn't fault anyone for using government stats (or at least not in this case). I see no intent to deceive anyone.
Of course, the circumstances of individuals who immigrated here varied greatly, depending on where they came from and how they got here - and what they could expect upon arrival. It's actually kind of fascinating when you consider it - the overall tapestry that makes up the fabric of America today. Some of it is kind of bloodied and battered, but it hasn't been all bad either.
Nevertheless, it's not necessarily the most important argument, whether for or against continued immigration in the present day. I don't think anyone is arguing that immigration be totally stopped, nor do I think anyone is arguing for totally open borders and letting in anyone who wants to come in. The whole argument is about degrees of difference - how much or how little immigration, as well as from which countries, not to mention those who come in legally vs. those who come in illegally.
