Heteros already have total acceptance. Sorry I don't feel I owe them anything and I'm not saying that unkindly. But I won't go out of my way to be nasty to them - for example if I see 2 heteros kissing in public I will be neutral about even ignore them. But don't expect me to smile at them though if I feel cheeky I may say "Can I join in?"..haha
Equality is more a legal/political issue - well it effectively comes down to that. I don't think you can really give equality. But you can respect others regardless of their orientation. Your post is a little confusing.
