According to the Osomatsu-san fandom, BLMatsu is basically incest?

But... but... I ship two things from it... and I hate incest smut stuff... (basically, I never ship things to that level)

Are you telling me my ships are just incest? But they're such lovely ships! ;^;

Also, I could easily discard it if it was obvious that BLMatsu was nothing more than incest (as in everyone has the same concept, so I can safely say my ships are not BLMatsu), but there are people (in our fandom) who take even casual ships as BLMatsu.

For example, a video about one of the characters talking/singing about how they love another character & wants to be with them forever is apparently considered BLMatsu?

;;--;; I already asked three people on SIT, my watchers on DV, and 8Otakutalia8 on DV (and haven't got an answer yet since I just asked). Seriously, this is ruining the shipping experience for me, bc you can't just call something as sweet as something like the example above "incest"!

Edit: Apparently, incest is a word used for a sexual relation between people who are too closely related. I always used that word for "erotic," though, so I hate having to accustom to this change. -_-
