"There even used to be a convention dedicated to sharing shotacon doujinshi, but, along with every other trace of a culture more tolerant of minor attraction, it too disappeared as its members became scared of the climate."
I've good news that this seems to be incorrect. I don't know a detailed history of shotaket or potentially any other shotacon conventions in Japan, so maybe they indeed stopped for a few years? In any case, shotacon conventions still happen, and there's even a documentary called Unreal Boys where the creator goes to one of them and sells artwork there he himself drew: https://www.youtube.com/watch?v=o4KPLOv2Iyo
The full documentary might be difficult or impossible to find online nowadays, but I definitely recommend watching it. It doesn't say anything about positive (or negative) about mapness from what I remember, though.
"I expect this post to do nothing. A couple people might read it and then go on about their day, but I can't just sit back and do nothing while I watch this community turn to shambles."
You know what they say, "Showing is more effective than telling." While there are a lot of difference, something vaguely resembling BeyondThePlus existed (or maybe still exists) in e.g. Prague, i.e. a MAP community that participated in pride parades from 2013-2019 or so or maybe even longer (I think they got eventually banned though due to antis pressuring the pride organizers if their Czech Wikipedia article is right).:
In 2014 a documentary was made about one MAP from the group and him spending time with other MAPs as well as attending Prague Pride: https://www.youtube.com/watch?v=6DgYq4SidV8
I think documentaries like these, or other ways to actually show MAPs and other paras what it is like to have an in-person paraphile community, can be very effective. So I'd recommend paraphiles who are on the fence whether to meet other local paraphiles or not to watch this documentary. Or even just watching your livestreams. Or Dutch MAPtivists speaking in front of students at a Dutch uni. Or even the documentary Chickenhawk since it shows MAPs spending time together, even though MAPs in it are portrayed very negatively and it's a very old documentary. Like, based on what I've seen how isolated MAPs react to seeing other MAPs hanging out they often get very excited about wanting to hang out with other MAPs too when previously they were quite hesitant.
I traveled to the US twice this year to meet other MAPs, and the second time I met with about 19 other MAP furs there. We livestreamed speeches at the opening ceremony of our meeting to a few other people in our small online group. One MAP who lives close to me saw it, and a few weeks later, once I was back from the US, met me, which was his first time meeting another MAP.
Perhaps you could do something similar at B+ meetings. Not necessarily a livestream to vetted potential future attendees who are on the fence, or recording faces (I presume that might be way to scary for most MAPs), but maybe some attendees would be willing to share their voices in a podcast session as part of a B+ meeting (at least when their voices are altered with AI) about how it is like to be part of B+ meetings that could later be edited and sent to review for everyone who participated, and then uploaded once everyone has given their OK to the B+ website. Or a meeting could have a doodling session and those sketches get later uploaded to the website. Or anything else that in some way shows what an in-person paraphile community can be like.
