Biased a bit, but I'd say that in relatively LGBT friendly places, bi can almost be more difficult than gay at this point. I've got family members who can be quite bigoted at times, who have now become totally fine with the various gay people they know, but have openly stated multiple times that bi people are just closeted/experimenting/deviant/etc.
Likewise, I have a couple of LGBT friends that legitimately get upset at bi people in hetero relationships, because they're "straight passing". It's utterly ridiculous, but definitely a trend I've noticed over time.
My folks are generally wholesome. I do have family members who are not onboard but like... We estranged from them largely for other biblethumpery reasons.
My coming out to my Grandparents was hilarious. My granddad with his hearing aids somewhere other than his ears was bellowing at the top of his lungs "(Chosen Name) IS A GREAT NAME KIDDO! I ALWAYS KNEW YOU TOOK AFTER ME! " as my Gran was like a minute behind the conversation and trying to clarify what was going down over the din granddad was making. It was like 15 minutes of utterly chaos that had me just dying with laughter.
But then they are all kind of cool. My 90 year old Great Uncle has a non-binary carer and went to his small town pride with his walker wearing a shirt that read "I'm 90 and I get it. What's your excuse?"
