Katie says she doesn't believe in ADHD. Michelle, despite being diagnosed with it herself, doesn't challenge Katie's view - instead she just says it's "over diagnosed", half agreeing with Katie.

Then Hopkins goes on to say Americans don't understand irony/sarcasm. Michelle just sits there silently.

Grow a backbone, Michelle. I thought she was meant to be ballsy?

At this point in time Hopkins could say being gay is a lifestyle choice and Michelle would just nod along.

Never, she is too scared to challenge her.

Nope, the most pathetic housemate in tthere and thats really saying something.

Her head is stuck firmly up hopkins bum. Its painful to watch.

The whole thing is just weird.

That ADHD "backdown" by Michelle was utterly pathetic. Coming from a woman who laughably believes she champions the underdogs and misfits? She is one of the weakest, most self-serving and dishonest people I have seen on BB, and that's going some. Absolutely hideous woman.

Well she knows / thinks KH is the most popular person with the public and I'd say that's the real reason.

She obviously isnt

Gonna keep this simple and answer with a no.

I'm waiting for Hopkins to slag off drag queens and Michelle to nod and smile

Maybe her desperation to win has overcome her principles?
She possibly heard Hopkins get cheered and thought that she couldn't go against her on anything. Much better to go against somebody with an unfavourable crowd reaction so that she's seen to be on side.

Which would go against everything she claims she stands for.

Maybe she does possess a sort of vague notion of some internet assembled principles that are seen to be right on and popular, that she may even use as a rough guideline of what's generally acceptable and what appears to be right and wrong. But it takes the slightest of things to make those principles evaporate into nothing. They appear to be very shaky at best.
But from what I have seen from her I haven't seen any principles of conviction and strong belief which she claimed to have gone into the BB house to speak up for.
A comfortable time in that house seems to be more important to her.
