Communication matters. Dialogue matters. If the brain isn't engaged and having fun, the rest of the body won't have much fun either.
Physical attraction is interesting. It's not just shape and size. It's dress, grooming, and how they carry themselves. If they are not attracted to each other, it's unlikely we'll be attracted to them. Conversely, if they make it clear that they are each other's best date and take pride in making sure they 'put their best food forward' for each other, it matters.
That's one of the reasons we list our shared values on our SLS profile. We don't want to waste time, or waste their time, with mismatched priorities and expectations. As for politics, we agree with you. In todays social and civil climate, staying tolerant of others' views takes more effort than it should. If it's fun time, we don't want to waste energy trying to look past opposing views. That does not mean we have to share identical perspectives, but it does mean that we are in the same clubhouse, so to speak.
