What is? i didn't say i believe the rumours but they were certainly widespread among people in the industry, so that's a statement that's neither 'true' or 'false', it just reflects what was going on at that time.
Perez built his website partly upon 'outing' gay celebs. He got a lot of criticism for it and from 2010 said he wouldn't do it anymore. Again, fact.
If I were a straight man who had been made uncomfortable in the past by rumours about my sexuality I would be wary of a rumour-monger like Perez who didn't alawys substantiate his claims.
If I were a gay man who hadn't felt able to come out, perhaps due to overwhelming pressure in my community to be a 'macho' man, then I would also feel very uncomfortable around Perez.
Finally, if I knew that Perez had access to very damaging information (which he has about a lot of celebs) then I would also feel very uncomfortable.
Either way, the discomfort was based on two very different ideas of masculinity and very different ideas of how you behave as a 'man'.

I've been wondering about why they didn't show his exit, and I think it must be because they couldn't cobble together a usable piece of footage.

Alexander probably talked about money from the off and maybe other stuff that BB certainly don't want to show us. He can't have done a half-baked 'please try and change my mind' speech - it must have been emphatic for him to have been out within the hour.

I just imagine that there was hardly a sentence that they could use to put in the HL show.

Shame really, as we can't be sure exactly why he left. He was so wound up, it would have been good to see.
