I get the frustration. I hope though that the opinion of the people who matter the most - i.e., your friends and family, and not random Internet strangers - will be based on who you are as a person, not on your identity as an American. Don't worry so much about the noise on social media, it's part of what got us into this mess in the first place.

At the same time, there are things you can do besides voting. Maybe you already know or do these things, but just putting it out there... You can call your representatives (and they might actually listen, if you're a Democrat in California), you can donate to candidates in other races if you have the means (there are probably going to be some pretty consequential senate races this year), you can join a protest (peacefully, and especially if you don't have any dependents).... And who knows, maybe none of these things will make a difference in the end, but I think the bottom line is that if you truly care about some of these things that are happening right now in the US, it's better to find ways to act on your convictions than to stay frustrated and fume online.

Just my 2 cents.
