I'd be interested to know "why not", since you've asked "why".
I signed it, but in truth I'm not too bothered being as in essence this is just a question of terminology (a civil partnership affords all the same rights as a marriage).
I respect your reasons and your opinions and you don't have to say them. As I said, I'd just be interested to know them, and you're right that you don't need to say them.
I don't see how "we should be allowed to get married" is more oppressive than that.
I also fail to see where the "liberal intolerance" lies in "I should be allowed to get married".
Anyway, this is nothing to do with left and right, as can be seen by looking at who supports what.
Cameron claims he "supports gay marriage because he is a Conservative", and the C4M countercampaigners* have amongst their spokespeople several Labour MPs.
*note, the C4M are against it, and the C4EM (whose petition this is) are for.
There are sentences in the bible (which may or may not be poor translations or additions over the years), such as a man shan't lie with another man (for it is an abomination). there are definately phrases in the bible which could be interpreted to mean that homosexuality is a sin (but interestingly, only for men, not for lesbian relationships). But then that still assumes that married people will always have sex (or "know" one another as I think it says). So that must mean marriage is fine if sex isn't involved.
Campaign for Equal Marriage website said:If marriage is redefined (again), those who believe in the modern definition of "traditional" marriage will still be married. They will still have the same sexual-orientation. Peoples' careers will remain intact, the sun will keep shining, and toast will still have a tendency to land butter-side-down. Couples seeking to adopt or foster will still be assessed based on the needs of the child, as they should be. Also, if we're very lucky, schools might teach kids not to be massive bigots like their parents, and we'll be one step closer to a cohesive, mature, civilised society.
