true but i don’t think they are actually trying to describe sexual orientation. this is a legal definition, for the language of the acts it is proposing to change. so it basically is saying “when you see ‘sexual orientation’ in the act, we mean ‘homosexuality, heterosexuality, or bisexuality’”

sidenote - i almost never see bills in such plain english. i was surprised because i have read a lot of legislation and much of it is so d e n s e (often, i imagine, to prevent regular people from understanding)
