For example, the bisexual community has the pink, light purple and dark purple, the gay community has the rainbow ect, are there no colours to represent heterosexuality?
Not sure we need any. Since heterosexuals are the majority we really don't need to distinguish ourselves from everyone else.
No, probably because homosexuals struggle with more discrimination than straights.
Best thing to do is just don't worry about it.
and all will be fine.
No such thing.......
