I see it as basically it comes down to common morals, character traits whatever.If someone you're interested in wants to do the opposite of your preference in the way of rights for a specific set of people that's probably not due to the specific group as it's more a not seeing eye to eye on on rights issues and there would be more to come in that relationship.
I'm straight but if I met a girl (passed that time forever hopefully) and she didn't want to give people the same rights as themselves, well yeah not going to be interested anymore. I don't even need a qualifier on people, we're all humans and deserve the same rights to love who we want and be the person we are (as long as it doesn't infringe on others besides their 'decency')
My girlfriend and I share lists on ours, she can add things and I can see them for when I go to the store. In theory cause she usually has to tell me.about it first so I remember to look at it. Makes Xmas food shopping much simpler. I suppose there is a text sharing one but so far 'ourgroceries' ( think that's right) only bugs me to buy the full app when I use it, but otherwise no biggie. Plus you can disable notifications from apps anyways, least I thought so, cause I probably had one from there and said nope, don't care. Maybe it tells you when someone else put something there if they are on, oh well if I'm missing them too cause we talk still heh.
