A wise man once told me that people are divided into apples and pears. Some people like apples and some people like pears. If you are a pear and someone doesn't like pears that doesn't mean there is anything wrong with you - you're just a pear.
If you don't like an act then don't vote for them.... simple.
There's no need for these vicious personal attacks.
Re John & Edward - it's true they can't sing but someone must like them or they wouldn't be voted in (I voted every week for Julian Clary on 'Strictly' - I knew he was rubbish but I loved seeing him)
