Are you more likely to get persecuted if you're bisexual than gay?

I find that more people are against bisexuality than homosexuality (with men) People that are against homosexuality are normally against bisexuality for the same reasons, but I’ve found with people I thought we very liberal and open minded that they’re against bisexuality. Almost always their reason is “They’re greedy.” Greedy for liking more but not necessarily having any sort of sexual relationship with more? Now if this is a point on numbers of how many groups of people that you could categorise do I like, could I say if I only fancied blond haired girls that people who fancy girls of different hair colour, they’re greedy? It’s such a loose point I’m shocked so many people hold this stance.
I’ve never have a legitimate relationship with a boy or a girl and I’m offended people would say that. My mum even said to me she doesn’t even believe in bisexuality and she’s one of the most liberal people I know. She started to set up dates with a gay guy she knows with me and I have never said I’m gay.
