The context is that he was posting on a news article about a fake police officer with SS tattoos carrying weapons to intimidate BLM protestors in Las Vegas.

I used samac.io to search his deleted comments.
A few more comments:


I don’t think that Graham Platner is claiming to be a communist anymore. He deleted the reddit account 3 months ago because he wanted to hide it. On October 17, he put out a video on his twitter account denouncing his reddit comments.
He’s running as a Berniecrat (unions, healthcare, housing, etc) but also against sending money to Israel. I think it would be foolish to think that he’s further Left than he’s claiming to be.
I don’t think he was a Hasan fan or Chapo or Trueanon. He did post Bill Burr a few times, which could mean anything. His main thing seemed to be posting on the Socialist Rifle Association subreddit.
A funny thing is that he used the Destiny-affiliated company to delete his reddit account. Destiny’s cohost Dan Saltman owns (redact dot dev) and was the former owner of TinyChat. Graham used redact to “delete” his reddit comments.
