I think that he has a good point, and is sometimes right. I think that if you are disagreeing with someone else about something you could be both right. Just like your favorite sport everyone could have a different opinion and it doesn't mean that either sport is better than the other. This video specifically is talking about places not in the USA they could have a different opinion or way of thinking than us but that doesn't make them wrong. One example was places while we might name the streets, Japan names the blocks in between the streets. Just because it is different from how you do it does not make them wrong they just think differenly and have a different opinion on it. Also like if you come out of a movie and your friend thinks the movie was really bad, while you really liked it. Neither of you are right or wrong you just do not think the same about it. But, in math when you are doing a problem there is usually only one answer. Like 2+2 is always 4. So just like the examples there is two ways of thinking on this video. Some people think it is right and others might disagree, but that does not make it wrong or wright people just have different opinions on it. So while you may believe one thing someone else in the world might believe the total opposite.
Here is the video, so you cansee your opinion on it.
