Every one of these, with the exception of the gay parenting is something I've encountered. I showed this to my boyfriend who is an activist and I've yet to hear his reaction. I'm pretty sure he'll say the same thing. Didn't Dan Savage play the "If you date someone of a different gender, you can't be bisexual anymore" card at a university he was speaking at?
They're forgetting "transmen/women are just gay men and women who are too cowardly to admit their same-sex attractions", assuming all transpeople identify as heterosexual. With bisexuality, there's no winning: date someone of same sex = gay, date someone of opposite sex = straight (or closeted, take your pic). There's quite a bit of policing in minority communities, like the parent who doesn't care what the kids down the street do, but would never entertain the thought of someone under their own roof doing the same.
On a completely different note, I dig the colours... a lot. So would we mark a square if we encounter something personally, or could we mark it if we've heard or read it, whether that's in person or online? If online reading counts, I think many people would have a completely marked card.
Bingo!!!! What do I win? ^_^ This game is actually quite depressing, because I have actually won twice from real life-personal experiences. I have had all of the contents of the vertical row furthest to the left and the horizontal row on the bottom expressed to me in person. Yeah, I think we would all have blackout then.
