I don’t live in the US and guns aren’t a thing here, but from what I know from my antifascist friends, owning firearms is a very good idea. They’re all armed to the teeth.

Unions and strikes

Ok, so serious answer for our friends who don’t live in places without an active culture of protest:

1. Vote. No, really. If people actually fucking voted, we wouldn’t be in this mess.

2. Give money to advocacy organizations

3. Give your time and money to mutual aid organizations

4. Read the news (not just on lemmy either)

5. CALL your congresspeople. Emails and letters are better than nothing, but do not have the same impact.

6. Try to get your friends to do #1-5

I think this one rings particularly strong today.

4. Take responsibility for the face of the world. The symbols of today enable the reality of tomorrow. Notice the swastikas and other signs of hate. Do not look away, and do not get used to them. Remove them yourself and set an example for others to do so.

historically? socialism.
