I have not been a part of the Linux community for very long but I’ve heard it a few times already, and since people usually don’t just pick random words as a post title, our brains start to look for any kind of connection a poster might have meant. Maybe an ootion for you would be to use very generic titles? Like “meme” or “image” maybe. I think this was mostly a really unfortunate coincidence, but I get that you’d rather just have a less political feed anyways.
