Blueink...naughty of you. Pick the analogy of 'play with the kids and do their bit at home' instead and it puts a different slant on it.
As Blueflowers has posted, a couple can have diametrically opposing views on a political party and still accept each other as people. I personally do not like arguing about politics and religion; starts wars ffs. I have no time for it so my partner is equally happy not to spend time on these subjects. My mother is another kettle of fish, I come away exhausted because she's very vocal on the subject and not only wants to know everything but also wants the opportunity to talk it through and change my mind.
It's the posters citing that they'd divorce that rankle with me; I think they're pathetic - and lying.
I've already said, you can end a relationship for ANY reason you like, however minor or major - and that would include politics and religion but I think most people look at the issues rather than the parties involved before reaching for their solicitors. I don't personally care if they don't, makes no odds to me but I think it's ridiculous.
If you look at the manifestos of ANY of the parties, what are the dealbreaker points exactly, (assuming that any of them would actually be honoured)?
I wouldn't tolerate racism, bigotry, sexism... any of those allied either. Neither would my partner and I knew that before I married him. How many people wake up one morning thinking, "Today, today I will see how many X people I can find to irritate". Not many, I'll wager.
I think this is going around in a bit of a circle and comparisons keep being made of things that are not easily or really comparable. Interesting as a discussion though.
