It's been a while since I've been to a US/Mexico game but, in my opinion, the experience is not that different from going to a heated NFL rivalry, as an example.

You'll probably see more stuff thrown onto the field at a US/Mexico game but the language and decorum in the stands is likely to be similar. But if you wouldn't take him to a big NFL rivalry game then I probably wouldn't take him to a US/Mexico game.

He'll hear things in the stands he may never have heard before, but I've attended about a half dozen US-Mexico games and never felt unsafe or even threatened by fans in the stands.

The journey from the seats to the car after the game might be the most dangerous part as all the idiots from both sides are pressed together and well lubricated. So may consider ducking out early or waiting until the crowds thin out.

I have seen Mexico play 4-5 times, a couple times against US, and I have never felt unsafe at all. It is a great experience. I would go and he will have a great time.

We decided to go and it was an absolute blast. I bought club seats and toward the very back of the section for an easy exit if SHTF. It was also under the overhang to prevent drinks from raining down on us.

We had absolutely zero issues with the Mexican fans around us. I was actually concerned because a handful directly in front of us showed up real drunk. The first time drinks started flying one of those same guys gave the people he saw doing it an ear full. They did take part in the chant that ended the game though.

Things did get dicey in the second half and there were several fights in the section over from us but luckily he didn't see any of it because he wasn't tall enough. The fights appeared to be amongst Mexican fans. I didn't see any Americans involved.

We took the advice from above and stayed for a bit after the game. During that time I bet 100+ Mexican fans came up to my son and fist bumped or shook his hand. A few groups started a "USA, USA, USA" chant

I was there, we were definitely in the minority in our section but got along well with all of the Mexican fans around us. It was a great time.

When I was coaching in Houston, most of my players were born in the US to parents who'd immigrated from Latin America. They mostly rooted for their parent's country of origin (a lot of Mexico but also Honduras, El Salvador, some Costa Rica and Panama too) but also followed and liked the US team. Because of that split loyalty, they were easily influenced by results. Whichever team was more fun to watch and won matches was the team they talked about and supported. It also helps to have cultural representation on the US team. Guys like Pepi and Jesus F. and their stories are recognized and respected by the young fans.
