The point is, we have our flags to symbolize the struggle for our rights, breaking away from the mainstream, etc. Straight and cis ppl don’t have to be told they’re unnatural, get kicked out of their homes, be made fun of constantly in the politics stream, etc. So, I do think that outside of LGBallT comics, flags for straight or cis (except for the ally flag, though even that’s controversial in queer communities), should not exist.
