I'm not 100% sure what you're looking for, since the two mangas you've mentioned are quite different, but here are some that deal with LGBT acceptance.

I love you two, keep spreading the quality works. I'll recommend this http://www.mangago.me/read-manga/ani_no_hanashi/ although I won't be surprised if you two have read it already.
Does it have to be a comic?
I want to read a material that has something to do with acceptance when one deviates from the societal norms. I guess I didn't point that out, huh? But I'm glad you caught it somehow.Thank you. I'll check'em out later.
I read it a long time ago. Re-reading made tear up a bit. The younger one is so precious. Thanks.
Not necessarily.
It's been a while since you posted this, but I came upon another manga just recently, so I thought I share it: http://www.mangago.me/read-manga/hourou_musuko/
I haven't read it yet, but after watching this review video (about the anime), I definitely will! https://youtu.be/lOQd05LGMMo
Thank you. I read this manga before and it was hard for me to breathe 'cause of crying.
Just finished "Smells like green spirit", which is btw a rewriting of today's behavior towards the LGBT community but with an exclusive focus on boyxboy. Well... Gossip has been a deadly sickness, however; no cure ever was found. I have also read "IS". If you can reccommend something similar that would be awesome. Tako approves.
