The idea of a romantic attraction, while I don't judge others romantic attraction; I hadn't always been directly attached to romantic dates. As I was beginning to discover myself, I went from deciding on being a demi-sexual, to then realizing I was more of an aromantic type. I had been made fun at for not going on dates, but not everyone was arophobic towards me and meet some nice and accepting people, after coming out as aromantic publicly.
I found out from their moderation history, that they were highlighted as being an alt right troll, regarding past comments they posted, which fits because they were seeming a bit off from the normal Lemmy user. They were also, so far, the only person to reply to the post on that community.
