Mixed views on the Amanda v Shane thing.
Amanda and Shane are both of a generation where they presumably had to disengage somewhat from what people thought on LGBT issues or they'd be unable to function, especially as neither were out until well into their careers. So they're going to have got used to the idea that it's possible for a person to want to deny them certain rights, but also quite possibly be personally kind and engaging to them. We can all have views on those coping strategies, but they are what they are.
Shane is quite right about Amanda not having the rights she does now if the likes of Ann had got their way, and neither Amanda nor Wayne have really shown any sign of being willing to acknowledge that. I can see why that would be frustrating for him, especially as Ann hasn't simply kept her views to herself, she's done things like rolling her eyes when he spoke about feeling a kinship with Wayne due to not being gay. Which was rude as fuck of her.
However, they also clearly both feel they shouldn't be expected to take on the mantle of being advocates for the community themselves- and rightly so, I think. Shane himself said that people from minority groups shouldn't be expected to be seen as representatives for their community on stuff like this, and yet I think he's expecting that from them somewhat. He's not expecting the straight housemates to call out Ann's attitude, after all.
I thought the whole thing was indicative of an age divide in the house, which I think has possibly been more of a thing than a divide of the sexes this year. Left me wondering has Shane J been round many LGB elders, especially women. I suspect he isn't that used to having heated discussions with 80 something lesbians.
