The great butter debate

We are a two butter household. Mine is left out in a covered butter dish at room temperature, my husband's butter is cold and rock hard inside the refrigerator.  I like salted butter, he likes unsalted.

He has changed my preference for syrups. I used to buy the awful artificial maple flavored corn syrup. He made his case and pure maple syrup is so much better. But I haven't been able to convince him on the butter debate. He was brought up in an anxiety ridden family that thought any dairy could spoil if left out for more than 5 minutes, while I was brought up in a more laid back household where something had to grow legs and start to crawl before we would start to worry.  I would explain to my husband over and over how we always left the butter out and never got sick. Yes- butter can go rancid if left out long enough, but being raised by two parents who both grew up on farms- we went through the butter quickly. I also would point out how impossible it is to spread cold butter on anything without destroying it. At my in-law's house you have to settle for smooshed dinner rolls with a cold pat of butter stuck in the middle. But that doesn't matter to him. 10 years of marriage and he still keeps his butter in the frig.  He hasn't put two and two together and figured out what butter I use to make his grilled cheese sandwiches.  Maybe I'll win if I make him make the grilled cheese sandwiches using his butter.
