Everyone is Bisexual Really

When it comes to bisexual visibility, some people say they've never seen, met or heard of any bisexuals. When they're told the person they're talking to is bisexual, they scoff. "Oh, you're bi, sure. You'll grow out of it. Everyone does! No-one's bisexual for life.". We disagree, and hope you'll find plenty of answers on this website to give these sort of people, if you do encounter this. 
The often quoted "Everyone is bisexual really" is utter rubbish! When people say this they hardly ever include themselves for starters. It's a phrase people use to dismiss bisexuality - after all, if we were the majority we needn't kick up a fuss.

When people use it they seem to mean "potentially" and talk about how we're born bisexual. This is either not true, or not useful. We're tired of trying to decide which.

It's about as useful as saying "Everyone's mixed-race really" when talking about ethnicity - it's not accurate in any real sense and doesn't provide any useful answers or usable insight when trying to combat racism or privilege.

Some people are attracted to only one gender. Some people are attracted to more than one gender. These two statements are not incompatible, and don't overlap.
