These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The New Normal
Acceptable Targets: ...Republicans. Often and without shame. From the first episode alone, when David and Bryan are interviewing Goldie:
David: Are you now or have you ever been a secret operative for the Republican Party?
Gary: We screen for that.
Hermaphroditic people, apparently, or at least those unashamed of it. In "The Goldie Rush," Gary says that all his attempts at dating have led him to "losers." Cut to one such date mentioning being intersex.
Which would seem more necessary if Modern Family weren't in its 4th season as one of the most popular comedies on TV...
A better example would be episode four, which makes it clear that one shouldn't vote based on race, but on issues.
"About A Boy Scout" suddenly mentions David was an Eagle Scout, and obsessively proud of the fact, pretty much so he could get kicked out and the show could make a "Gays should be allowed in the Scouts" message.
Broken Base: The fifteenth episode "Dairy Queen" split the fans right in two. Either you'll laud it as a surrealistically funny episode or a giant, embarrassing trainwreck full of squicky, slightly-incestuous undertones.
In a meta-sense, the entire show when it comes to Republicans. It's a show about a gay couple having a child, with Republicans being an Acceptable Target. That will annoy the far right on its own. And then you factor in the fact the show premiered on September 11th and you can't help but think they're trying to antagonize the people who would be offended by the show.
Fridge Logic: in The XY Factor Bryan says that he wished the child was a girl because he doesn't know how to relate to other men, and points out how out of place he felt as a kid with his family... including his sister. Who exactly could guarantee him that, even if the child would be female he won't be that she'll turn out as girly as him? She could've been as butch as Bryan's sister.
Strawman Has a Point: When Jane asserts that marriage isn't for children, dogs, or gays. Two out of three, really. Kids having a playground wedding during recess or pet owners breeding their animals is one thing. Hiring caterers and planners for these occasions is pretty ridiculous, even for the affluent.
