I don't really, just pointing out the absurdity.
What I really think is that we aren't saying people can't have opinions, just that our opinion is that their opinion is stupid.
Well say I disagree that other people should be allowed to have an opinion. That's my opinion. Which you've just said everyone is entitled to have. There's an inherent contradiction right there.
Where do we go from here?
There was a gay guy who lived with his mum and his massive dogs up the road from me when I was a kid called Barry Scott. I don't think he was a footballer, though.
