I'll concede my original point. I was wrong about her race, nationality, and accent. Looking back, that was my own unchecked prejudice. I made an assumption based on how she looked and spoke, and I shouldn't have. That's on me.
That said, I think you're doing something very similar when you confidently assert that she was treated differently because she was white and Christian. The video doesn't establish that. It's an inference about the motives of the airline staff, not evidence. You're presenting speculation as though it's a proven fact.
As for Executive Order 13769, that isn't really relevant here. It was an executive order signed by Donald Trump restricting entry into the United States from several Muslim-majority countries. It was enormously controversial, challenged in court, and widely criticized as discriminatory. But it was an immigration policy, not a policy directing airlines to remove Muslims from domestic flights. Pointing to an unpopular executive order from an administration that many people already viewed as racially insensitive doesn't demonstrate that race or religion were the deciding factors in this completely separate incident.
If your argument is simply that she should have been removed from the plane sooner because she was causing a disturbance, I can understand that position. But claiming she received preferential treatment because she was white and Christian requires evidence specific to this incident, not assumptions about the motivations of the people involved.
Edit: One more important point, because I think a lot of people get this confused:
The United States is not the Donald Trump administration. There are tens of millions of Americans who do not support what his administration is doing and actively oppose many of its policies, including me.
Please don't take the actions of one administration and attribute them to the American people as a whole. The United States is a nation of over 330 million people with a wide range of political beliefs, and no single administration speaks for every American.
