Lot of discussion on FOX about this.
Many former players of the USWNT take the Anson Dorrance approach that by playing as hard and as well as you can for the entire game, you are showing your opponent full respect. Current veteran players, Alex Morgan and Megan Rapinoe, emphasized the joy of this being the World Cup and how players (especially the new ones) are scoring goals they've dreamed about since they were young. There's side mention of goal differential as a tiebreaker. Coach Jill Ellis hints that this wouldn't be discussed in a mens game.
Foreign players take a much harsher view of the game. A former Canadian player ripped the US approach for both the number of goals and the celebrations. A former England player notes that the goals were part of sharpening the offense but celebrations after 5, 6, 7 goals crossed the line. Former 2x German World Cup champion had no problem with the number of goals or even celebrations by first-time players, but she found displays by veterans like Morgan, Rapinoe, and Lloyd to be lacking class.
Former USMNT player, Lexi Lalas, had no problem with the goals or the celebrations. To the contrary, he loves anything that gets people talking about soccer. But he also notes that a game like this makes the target on defending champions even bigger.
Consensus from the panel was that this discussion was entirely about sportsmanship and had nothing to do with sexism.
When I first began coaching high school in Cincinnati (1990's), the unwritten (but often discussed) rule among coaches was that you didn't allow your team to win by greater than 10-0 (I know others believe this number is too high). Other parts of the state (especially Dayton) do not abide by this. Personally, as a coach and player parent, I have found nothing more distasteful than keepaway. I also never played short-handed, because I wanted to get my substitutes opportunities to play. I could almost always put the brakes on the scoring by, after a certain number, requiring all goals to be scored on headers by players who had never scored before. Regardless, I think it's most important that you emphasize respect for your opponents. I suspect the reaction towards this game will impact future USWNT blowouts.
I have yet to see comment from Thailand on the game, and I'd be interested in that. One reaction from a Thai player living in the US is in this article:
