It goes back to the fact that people in this fandom (both guys and girls) tend to have been the nerdy type who didn't get a lot of attention from the opposite sex growing up. A lot of us have never been in a relationship, and for those who did, these were not gratifying. This led to many swearing off marriage, children, etc. and/or transitioning to the opposite gender in the hopes of improving oneself. If any of these girls just had a guy who loved and cared for them properly, they can be saved. Same goes for incel guys, btw. If you see a chubby femcel type girl, don't just write them off. If you two can exercise and improve your lifestyles together, you can get yourself a good looking girl. Being fit is about 75% of being attractive.
