There are social events and league matches, whether they are USTA, ALTA, or other. These events and matches should be very different IMO.
I see three types of players/teams in mixed:
1) Win At All Cost - WAAC
2) Out for Fun - OFF
3) Play As Required to Win - PAR
Some people have a win at all cost approach every time they step on a court whether it is a social mixer type setting or a match - these people are clueless IMO - imagine the hard hitting 3.5 guy who wants to be a 4.5 going all out playing against a 3.0 lady in her mid 60s- ridiculous ? Yep. but we have all seen this more than we care to admit. Then there are other players are clearly out on the court for fun with no expectation of winning.
These three types of players/teams all win and they all lose - the latter group is the group I consider the most fun in mixed. The problem is two of the subsets of players/teams don't mix well in mixed doubles - that being the Out for Fun vs The Win At All Costs.
WAAC is acceptable in a league match IMO (although many players including me choose discretion and throttle back to used a PAR approach.) If you are playing 6.0 and you can't handle the heat, then you really can't blame the opponent for doing their best to win. A weak 3.0 lady can accept the beating and work to improve her game or skip league matches. They keep score for a reason, so stop whining about guys hitting too hard. They have the right to go all out, even though many of us think they could/should throttle back when pummeling a weaker team.
WAAC and OFF being on the same court simultaneously is like herd animals crossing a river swarming with crocodiles. The crocs need to eat once per year, but they never pass up a meal.

The conflict happens when when these groups meet and the WAAC can't or don't tone it down for the OFF teams.
My approach is to gauge what group I am playing against. If you are playing the Defending 7.0 State Mixed Champs in a local playoff match, with strong 4.0 guys and strong 3.0 women, or two strong 3.5 players - it is game on. However if you are facing a clearly inferior opponent, have some class a dial it back a notch.
Do what you need to win, but have the situational awareness to throttle back when you are beating a team 40-0, 40-5 game in game out, and up 6-0, 2-0 with the last three games 40-5, 40-0, 40-0. I don't advocate throwing games, but restraint goes a long way IMO.
Just my perspective on mixed from a 4.0 guy who has played on very competitive 7.0/8.0 mixed teams.
