A tiny noose hangs from mirror

I took my mom to the bank today. And where we live in the high desert we're a really distributed minority. Actually you rarely see hispanic people. Probably the only place you will see Hispanic people is the Spanish mass they hold on Sundays. And I don't know if it's my imagination or if I read too much into it but there is always a teacher that greets all the kids when they're dropped off... I see her say hello to all the kids ... well with exception of my son. My son doesn't really look hispanic most people confuse him for being mixed (or I don't know if they still do but they did) but he's Hispanic (I think, fully, I think haha). And Every morning I see her and she greets all other kids but she never says a word to my son. It's not that I'm going to make her, it's not the point but it makes me wonder why she skips him... maybe it's because he's small and his mission is going straight to class and wont acknowledge her. But, then again to other kids who aren't looking she'll greet them and even say hello to the parents in the car. I don't have a a great car but it's nicer than some other's but that's not the point she never greets me either. I guess the wonder just comes to my mind.
I do have to say though when I went to the University I went to one which was predominantly white, all the people were great and I never felt like an outsider or the need to join a Latino group or a minority group, I did what I could to fit but I did see a lot of friends struggle instead of adapting which always made me sad. I know what it feels like being the only mexican and female in a crowd of 100+ , having my personality I will say I felt a little rather odd especially when I feel I don't fit but I make the best of the situation but school gave me comfort and security. Now where I live now, it's hardly liberal... very very conservative. I actually feel awkward at times even when I go grocery shopping... it can be my imagination... or is it? I guess it's a time when I'm finally happy we're moving back to what I know has been home since June 1998. Don't get me wrong... I love it here, the beauty of the high desert, the wind, the cold evenings, the fresh air, the view of the mountains, the long drive down. I love the house we have here,the space... But, the eyes of people staring... or am I going crazy... but I've lived here for like year and a half and those staring eyes should have ideally stopped but nope. Maybe I'm paranoid...
Anyways enough of my tangent so I took my mom to the bank. And while I was there my son started crying because he was hungry. He had just gotten out of school. I was just looking back to talk to him and reassure them that it was a quick stop so a white car pulls up next to me and parks. I did a double take when I saw this man... he was wearing this bandanna ↓

I was curious so I think I kept somewhat looking while still trying to calm my son. I think he felt my brief stares... lol  but what's not to look at especially when you notice what he's wearing on his head. I think he had a bad day because he looked rather upset. So I know he looked my way a few times... And then he went into the bank...
I get bored to I just look around and play with my phone. But, since I can't do much with my phone (only in that area- poor service) I just look distracted. So, I look into cars ...

So I was looking into this guy's car who just happened to go into the bank and since he was already wearing a bandanna with many confederate flags... I just stopped thinking about it... out of sight, out of mind until I see what he had hanging from his front mirror. It's a little noose... I don't know and I didn't want to jump into conclusions but I found it oddly funny. (oh yea, and that's the picture of his car, I took... it was too good to pass up of a pic. I almost took a pic of him as he was sitting but I thought that would be too obvious)
I can't assume anything (even though you know what I'm inferring , I think) but what would you think... *shrug*
