It is still perfectly legitimate to express a view on the rights and wrongs of it.  Unless we move into dictatorship, the right to express an opinion will always be sacrosanct here in the UK.  The right to express a evidence-supported one is not only a right, its a scientific requirement.

Nobody here, but nobody has suggested that you do not have the right to express a homophobic view. It's just that everybody else also has the right to name it 'homophobic' and, more to the point they are in the right when they do so.  You have never been able to back up your prejudice with evidence.  Many people have challenged you to do so and, on the rare occasions that you have presented anything, on closer analysis the evidence has undermined your stance rather than supporting it.
