You misunderstood me, maries. I do respect people's right to believe whatever they want to believe and I respect people. That's different, and quite separate, from whether I respect the beliefs people hold. I respect your right to argue your case in favour of not changing marriage law, just as I expect you to respect my right to argue in favour of changing it to accommodate homosexuality.
For me, the logical bottom liner on this issue is how ironic it is for the Church of England, set up because Henry VIII wanted to change the "concept of marriage" to suit himself – no till death us do part for him if he couldn't get a viable male heir out of his 'proper' wife – is now squawking about other people wanting to change what marriage means.
