We've all seen Biggins on BBOTS, I'm A Celeb and so on, and I think we have a pretty good idea of the man that he is.
And from that I believe he has just been an arse, got too comfortable and thereby unguarded, saying things probably best only said when amongst friends.
To be offensive, there has to be some intent; if Bear made the shower joke (and we still have no confirmation of what Biggins actually said), then we'd know the intent was to be nasty and, yeah, classable as offensive. Coming from Biggins, you know it's just gallows humour and if whatsername really was in tears about it, then she needs a sensitivity bypass.
His views on bisexuals are ridiculous and totally without merit; but offensive? I'm not offended by them - are you? Really? In the grand scheme of things, are those the most offensive views you have heard recently?
If holding ridiculous views was a crime, 90% of the population would be in prison.

Oh oh oh someone said something stupid, let's jump on them and make ourselves feel good by being as judgemental and superior about it as we can - burning at the stake isn't good enough.
