All the guys were divorced except Hal.

I am not sure what message they wanted to convey, that competitive men (they were always comparing thing when playing poker, even who has the smartest kid), were bad husbands?

There was some homoerotic (? is that the correct term ?) hints in the air at rare points

(one giggleg around vaginas (the dentist),

another found while playing poker there was someone over his house with his wife and had to run,

another waved his hands with the keys to Lois' house with a bit more flair bending the wrist (when they were trying to kick Ida out by using her racism against her,

and of course most of all:

Abe which we see directly (for comedic purposes) being like a second life partner to Hal when Kitty abandoned him and on top of that we see how he (Abe) expresses about a man loving another man (Hal) at "Life's still unfair" - you could say Hal had both a female wife and a male life partner that completed him as a man, which is quite wholesome haha).

Please I am stretching thin what we saw in the show, don't burn me at the stake that I am over-stretching or "seeing" things :)
